Prescreening of compounds
From just a sketch of the molecule structure, the chemist can calculate properties such as UV and IR spectra, dipole moments, ionization potentials, heats of formation, Gibbs free energies, transition states, reaction pathways, susceptibility to electrophilic attack, etc. WinMOPAC enables the chemist to prescreen numerous possible candidates faster than synthesizing just one, so saving valuable laboratory time.

New Insights
Visualization of chemical reactivity can offer unique insights into reaction mechanisms and chemical processes that are unavailable from other techniques. WinMOPAC complements analytical chemistry by enabling the chemist to experiment with new catalysts or reaction conditions in just moments on a personal computer.

Teaching chemistry
3D visualization of electronic structure and chemical properties makes WinMOPAC one of the most powerful teaching tools available. Interactive 3D graphics provides a far clearer understanding of chemistry than the static images in slides and books alone. The student can now interactively visualize reaction mechanisms and study the relationships between chemical properties and structure on a personal computer. New concepts and ideas can be tested immediately.

Reputation and science
WinMOPAC is based on MOPAC, which is the most widely distributed semiempirical quantum mechanics program in use throughout the world, with over 50,000 licensed copies. MOPAC has been developed over the past 15 years under the direction of Dr. J. J. P. Stewart. WinMOPAC is fully supported by Fujitsu Limited and runs under Windows NT, 95, and 98.
