Hyperchem 8.0 Professional
HyperChem is a sophisticated molecular modeling environment that is known for its quality, flexibility, and ease of use. Uniting 3D visualization and animation with quantum chemical calculations, molecular mechanics, and dynamics, HyperChem puts more molecular modeling tools at your fingertips than any other Windows program. 

Our newest version, HyperChem Release 8.0, is a full 32-bit application, developed for the Windows 95, 98, NT, ME, 2000, XP, and Vista operating systems.  HyperChem Release 8.0 incorporates even more powerful computational chemistry tools than ever before, as well as supporting multiple third-party applications. Its drawing and rendering capabilities and ease of use are standards for the industry.

Molecular modelling Pro
Molecular Modeling Pro: 3-D modeling, database creation / manipulation and calculation of chemical properties from structure. Easy to use, reasonably priced! Draw structures with a mouse. Minimize them with MM2, MOPAC or MOLY. Do conformational analysis of 1-2 rotating bonds. Calculate over 120 chemical properties from structure. Save structures, reactions and calculated properties to databases with automation. View the databases and edit the data. Interacts with ChemSite including display of molecules in MMP databases with ChemSite. Automatically generate HTML pages with rotating structures.
