                             MOPAC2009™

MOPAC2009™ is the successor to a MOPAC2007™, 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^®, Linux and Macintosh 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, including the new PM6 method which was parameterized primarily for biochemistry. MOPAC2009™ now includes a linear scaling algorithm for geometry optimizations on systems of up to 15,000 atoms such as proteins, metalloenzymes, and segments of DNA.
                                                                            more details...

                   MOPAC2009™ for CAChe

Users of the CAChe Worksystem, BioMedCAChe, and Quantum CAChe, etc. can now upgrade to the latest version of MOPAC2009 with PM6. MOPAC2009 handles many more elements than MOPAC2000; a total of 69 for PM6, 42 for AM1 and PM3, and 15 lanthanide sparkles, while PM6 provides significantly improved accuracy over the older methods. Existing CAChe procedures for the old PM5 method in MOPAC2000 will automatically use the new PM6 method in MOPAC2009 (PM5 is replaced by PM6 in MOPAC2009). The MOPAC2009 upgrade is available for both annual and permanent CAChe licenses, and is compatible with most versions of CAChe 6.x, 7.x, and later. To test your CAChe installation with the MOPAC2009 upgrade, download the free demo version:

       DEMO version works with 1-12, 50-60, and 110-120 atoms only. To restore your original
       version of MOPAC, follow the instructions in the installer to rename the original MOPAC
       compute engine before installation, or use your original CAChe CD to reinstall CAChe.
       "MOPAC2009 for CAChe" is produced by Stewart Computational Chemistry LLC, USA which
       has no relationship with Fujitsu Ltd, Japan, the owner of the CAChe products.

                                 PARAM™

              High-accuracy custom parameterization

The methods in MOPAC^® can achieve higher accuracy for thermodynamic properties, comparable to many high-level ab initio methods but much faster,
by re-parameterizing for a subset of elements or compound classes. PARAM automates and dramatically speeds-up the tedious and time-consuming parameterization process and, it comes complete with the extensive sets of experimental and DFT reference data used to parameterize PM6, PM3 and
AM1. Developed over many years by J.J.P. Stewart, PARAM has now been released as a supported software tool.

Custom re-parameterization is also available as a contract service. Please contact Mopac@CACheResearch.com for further information.
