Ghemical software free download is a computational chemistry software package and has graphical user interface based on GTK+2 and supports quantum mechanical and molecular mechanic models, with geometry optimization, molecular dynamics, and a large set of visualization tools. Ghemical relies on external code to provide the quantum-mechanical calculations — MOPAC provides the semi-empirical MNDO, MINDO, AM1, and PM3 methods, and MPQC methods based on Hartree–Fock calculations.

The chemical expert system is based on OpenBabel, which provides basis functionality like atom typing, rotamer generation and import/export of chemical file formats.

features of the Ghemical program:
