Jmol is an open-source Java viewer for chemical structures in 3D, with features for chemicals, crystals, materials and biomolecules. Jmol is a free, open source molecule viewer for students, educators, and researchers in chemistry and biochemistry. It is cross-platform, running on Windows, Mac OS X, and Linux/Unix systems.
1. The JmolApplet is a web browser applet that can be integrated into web pages.
2. The Jmol software is a standalone Java software that runs on the desktop.
3. The JmolViewer is a development tool kit that can be integrated into other Java applications.
