Jmols

Jmol is a free, open-source Java viewer for chemical structures in 3D. It is widely used in chemistry, biochemistry, and related fields for visualizing and analyzing molecular structures. Jmol is designed to be platform-independent, and it can be run on various operating systems, including Windows, macOS, and Linux.

Jmol's capabilities include rendering 2D and 3D structures, displaying molecular properties such as bond orders and stereochemistry, and calculating molecular coordinates and distances. It also supports various file formats, including PDB, MOL, and SDF. Jmol allows users to rotate, zoom, and animate molecules, as well as to highlight and manipulate individual atoms.

Jmol has been developed since 2004 by Bob Hanson of the Chemistry Department at the State University of New York at Albany, and its code is continuously improved by a community of developers. The software is released under the GNU Lesser General Public License, making it free for individuals to use and modify.

Jmol has found use in various educational and research contexts. It is often used in teaching molecular chemistry and biochemistry, as well as in research laboratories for analyzing and visualizing molecular structures. The software has also been integrated into various molecular modeling and simulation tools, allowing for seamless interaction between different components of a research workflow. Overall, Jmol is a widely used and versatile tool for visualizing and analyzing molecular structures.
