MOPAC2009™
What's new in MOPAC2009™ ?


MOPAC2009™ is the successor to MOPAC2007™ and includes the new capability to optimize systems of up to 15,000 atoms, such as proteins.

• Optimize giant molecules up to 15,000 atoms, e.g. proteins
 • PM6 parameterization using experimental and ab initio data
• More accurate* heats of formation and geometries
• ALL main group elements & transition metals parameterized
• Serious errors from PM3 and AM1 corrected
• Crystals, surfaces & polymers with periodic boundaries
• FREE to academics

MOPAC2009™ is a semiempirical quantum chemistry software package for the prediction of chemical properties and modeling of chemical reactions. It is used by chemists and biochemists for both research and teaching, and runs on Windows® and Linux platforms.

MOPAC2009™ is a completely updated and rewritten version based on the public domain MOPAC® 6 with many bug fixes and several major enhancements added.  MOPAC2009™ was developed independently of any commercial versions of MOPAC®.  Customers with MOPAC2007™ support will be able to upgrade to MOPAC2009™ at no cost.
