Jmol: An interactive viewer for three-dimensional chemical structures.

Description
Over 10,000,000 page views! Jmol/JSmol is a molecular viewer for 3D chemical structures that runs in four independent modes: an HTML5-only web application utilizing jQuery, a Java applet, a stand-alone Java program (Jmol.jar), and a "headless" server-side component (JmolData.jar). Jmol can read many file types, including PDB, CIF, SDF, MOL, PyMOL PSE files, and Spartan files, as well as output from Gaussian, GAMESS, MOPAC, VASP, CRYSTAL, CASTEP, QuantumEspresso, VMD, and many other quantum chemistry programs. Files can be transferred directly from several databases, including RCSB, EDS, NCI, PubChem, and MaterialsProject. Multiple files can be loaded and compared. A rich scripting language and a well-developed web API allow easy customization of the user interface. Features include interactive animation and linear morphing. Jmol interfaces well with JSpecView for spectroscopy, JSME for 2D->3D conversion, POV-Ray for images, and CAD programs for 3D printing (VRML export).

Requirements

The Jmol web browser applet may run on most browser Java Virtual Machines, including the Microsoft and Netscape 4.7* implementations of the Java 1.1 JVM. If you are running Microsoft Internet Explorer on the Windows operating system you should upgrade to the Sun Java Virtual Machine (see below). 

The standalone Jmol application requires Java 1.4 or higher.
