What is MOPAC2016 ?

MOPAC2016 is the successor to MOPAC2012. MOPAC2012 will no longer be supported.  Customers with MOPAC2012 support will be able to upgrade to MOPAC2016 at no cost.

What's new in MOPAC2016 ?

Improved handling of large biomolecules. This includes the ability to more easily manipulate macromolecules, e.g., to ionize and de-ionize individual atoms and residues, superimposition and calculation of RMSD for pairs of systems, and easier specification of individual atoms.

New in MOPAC2012TM

• The semiempirical method PM7.  This has improved accuracy for systems that were not used in the parameter optimization process.

New in MOPAC2009TM

The MOZYME function.  This is a linear-scaling SCF technique suitable for modeling proteins

New in MOPAC2007TM

• NEW parameterization (PM6) 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
