You seem to have CSS turned off. Please don't fill out this field. JSmol is the extension of the Java-based molecular visualization applet Jmol jmol. JSmol can read all the files that Jmol reads. You can do all the scripting that Jmol does. You can create all the buttons and links and such that you are used to creating for Jmol. All of the rendering capability of the Jmol applet is there. JSmol has both a console and a popup menu.

A "lite" version of JSmol provides minimal functionality balls and sticks only for extremely small-bandwith apps. JSmol Web Site. Do you have a GitHub project? Now you can sync your releases automatically with SourceForge and take advantage of both platforms. JSmol took us out of the bottleneck of Java security restrictions and platforms lack of support. So we can continue developing web materials with the excellent and ever expanding capabilities of Jmol.

As a Jmol Web page application developer, one problem has always bothered me. Java browser plugins can be a real nuisance for users. For more than a decade, this nuisance was worth the effort because Jmol was the molecular visualization gold standard. With the decline of the Java browser plugin There, I said it! It simply goes by a different name, JSmol. If the Java plugin tickles your fancy, that's just fine.

JSmol will render as the familiar Jmol applet. It also brings Jmol's powerful molecular visualization to the mobile device sandbox. Your iPad is no longer limited to "watching the pretty molecule spin. The key to this cooperation is the powerful scripting language. Users do not have to worry about low level programming. They can develop applications by working in Jmol's high level scripting environment. As a chemist, I have always thought of this scripting language in this way: I do not speak Jmol's language.

Jmol speaks my language. I must admit that I'm happy to free my users from the Java plugin hassle. There, I said it again! I am, however, absolutely excited about moving into the realm of mobile devices.


I have no doubt that the historic cooperation between developers and users will lead to some pretty creative things using JSmol in the mobile environment. We're not going to be doomed to simply "watching the pretty molecule spin. Otis Rothenberger. Please provide the ad click URL, if possible:.

Services Business VoIP.Jmol is an open-source Java viewer for three-dimensional chemiscal structures, with features for chemicals, materials and biomolecules. Features include reading a variety of file types and output from quantum chemistry programs, and animation of multi-frame files and computed normal modes from quantum programs 1.

The tutorials in this course use Jmol to allow the reader to open molecules usually pdb files and view them interactively. Java is required on the computer that the tutorials are being viewed from and javascript must be enabled from within the browser being used.

Two things are required to view the molecules in this tutorial; java must be installed on the computer, and javascript must be enabled in the browser used to view the tutorials. Throughout the tutorials, clicking the links labeled "View this molecule interactively" will open new browser window in which the Jmol Applet will start and display the molecule.

Getting Started in Jmol

Jmol What is Jmol? Obtaining, Installing and Using Jmol Two things are required to view the molecules in this tutorial; java must be installed on the computer, and javascript must be enabled in the browser used to view the tutorials. Some tutorials require that the individual download and view pdb files of the molecules described in the tutorial.

A stand-alone application of Jmol can be downloaded and installed for this purpose. This page provides instructions for installing and running Jmol. References Jmol: an open-source Java viewer for chemical structures in 3D.JSmol can be used as an alternative to the Jmol java applet, because it is written in javascript it does not require Java but instead renders the molecular models in a webpage using just JavaScript and HTML5 features.

JSmol is not a different program than Jmol: it is Jmol, just compiled into JavaScript instead of Java, and thus those who are familiar with scripting Jmol will be very much at home with JSmol. Everything you need can be downloaded from here. The structure below is rendered using JSmol, if you click and hold down on the mouse you should be able to rotate it, alt-click rotates in the z-plane, shift-click is zoom or you can use the scroll wheel on your mouse.

If you right-click on the structure you should see a drop down menu displaying all the usual Jmol options. One consequence of this is that the javascript files are quite large and do take a a few moments to download.

In my experimentation I found it all seemed to work as expected, including dot and and translucent surfaces, distance and angle measuring, there is a more fully featured test page here. This conversion from Jmol to JSmol is excellent with the credit going to the people named below. WebGL interface written by Takanori Nakane. Java2Script written by Zhou Renjian, et al. Jzlib written by Atsuhiko Yamanaka. Jmol code conversion to JavaScript by Bob Hanson. GLmol is a 3D molecular viewer based on WebGL and Javascript, and again it is possible to display structures in a web page with out the need for plugins or java applets.

In Safari, open the Safari menu and select Preferences, then, click the Advanced tab in the Preferences window. At the bottom of the window, check the Show Develop menu in menu bar checkbox.

The molecules can be rendered as ball and stick, or line format, and the secondary structure of proteins can be displayed in cartoon format.All the functionality of Jmol as a standalone application is also present in JSmol. This is a still image, but you can see several animated displays of Jmol abilities by clicking here or on the image itself. The JSmol library may take some seconds to load. Please, wait and do not reload the page in the meantime.

Here you can see the JSmol object in action, running a script written in the Jmol scripting language. It is not a movie, slide show, or animated image file JSmol is an interactive web browser object. Jmol is a free, open source viewer of molecular structures useful for students, educators and researchers in chemistry, biochemistry and other fields dealing with molecular structure.

The recommended way to cite Jmol is: Jmol: an open-source Java viewer for chemical structures in 3D. Remember to always use uppercase ' J ', lowercase ' mol ' explanation. If you prefer, a list of articles that describe Jmol can be found in the Jmol Literature section of the Jmol Wiki. Check out the Screenshot Gallery still images to see samples of what can be done with Jmol and the Demonstration pages to see buttons and menus in action interactive object within the webpage.

Being a. If you want a Jmol icon to be shown instead, you can get it from the Jmol Wiki. A handbook has been published for learning Jmol, and there are also other publications about Jmol. There is also a list of tutorials designed to learn the use of Jmol, and more help, within Jmol Wiki. Finally, there is a documentation section in this web site, for more technical details. You can also learn by examining web pages that use Jmol: demonstration pages within this web site, and a list of websites using Jmol in Jmol Wiki.

A user-maintained site collecting a lot of information about the use of Jmol. More dynamical and frequently updated than this web site!

Various ways to create surfaces and more documentation on surfaces. Displaying shapes, polyhedra, orbitals, dipoles, distances, forces and vibrations.

Creating movies. Web pages without writing code by using the Jmol "Export to Web" function.This page provides help on using the JSmol 3D viewer. JSmol is one of the key "applets" used in ChemInteractive. Much of the analysis of structures that users draw is carried out by JSmol, but that work is carried out behind the scenes, invisible to the user.

However, JSmol is also very useful as a learning tool because it allows the user to rotate and scale structures, and to display them in several different styles. These features are very helpful for visualising the three-dimensional shapes of molecules, and understanding shapes is crucial to understanding some properties of substances.

JSmol can also be used to view other chemically important objects, such as orbitals, in the same interactive way. Moreover, measurements such as bond lengths and bond angles can easily be obtained. To check your JSmol skills, try the exercises that are suggested at several points below.


JSmol is compatible with all modern browsers Internet Explorer must be version 9 or later on almost all computers, tablets and smart phones. The JSmol applet should be visible below left, and a molecule should be displayed. If the molecule is not visible, try reloading the page. If it still does not appear, check that JavaScript is enabled in your browser. In this view atoms are represented as small spheres, and bonds are shown as cylinders connecting the spheres.

Note that all atoms, including all hydrogens are shown, and the elements can be identified by a colour coding scheme that is very commonly used: C is black, H is white, O is red, N is blue, S is yellow, etc. Rotate the molecule simply by clicking anywhere in the window and dragging the cursor. Zoom in or out using the mouse wheel, or by holding down the Shift key while dragging the cursor vertically in the window.

Try Exercises 1, 2 and 3 below to check your mastery of these basic features of JSmol. The space filling representation is more "realistic" in that it represents the molecule as a set of overlapping spheres. Experiment with other settings in the Atoms and Bonds submenus. Various representations of the "surface" of the molecule can be accessed from the Surfaces submenu. The most electron-rich negatively charged areas are coloured red, and the most electron-poor positively charged are coloured blue, with shades of yellow and green in between.

Try this now and then try Exercise 4.


Bond angles can be displayed in a similar way. Experiment with this feature and then try Exercise 5. JSmol has many other powerful capabilities, such as the display of orbitals and molecular vibrations provided that the relevant data are available for the molecule.

Take a look at the companion site Molevision to see some of these features in action. Learning Outcomes On completing the exercises you should be able to:.
