Ghemical is a molecular modelling software package with GNOME and GLUT GUI front-ends and some nice 3D-visualization tools. It supports methods based on both molecular mechanics and quantum mechanics using MOPAC7 and MPQC for QM. Algorithms for geometry optimization (for MM and QM) and molecular dynamics (for MM) are included. Ghemical is written in C++, and offers a good framework for a generic freeware molecular modelling tool.

Ghemical uses the OELib/Babel C++ framework for import and export of a range of chemical file formats.

As the version number indicates, Ghemical is still in development, though it is already quite usable. Feedback, suggestions or contributions are very welcome. The program is made available under the GNU GPL and is free software.
