ANNC: Mopac 2002 now available from Schrodinger



Schrodinger, Inc. is pleased to announce the release of Mopac 2002 for Unix
 (including Linux). Mopac, the most widely used semiempirical quantum mechanics
 program in the world, is a general-purpose package for the study of chemical
 properties and reactions in gas, solution or solid-state. Mopac 2002's linear
 scaling algorithms, including the patented MOZYME algorithm, allow it to
 efficiently study systems up to 20,000 atoms, making it particularly suitable
 for proteins and DNA.
 Mopac 2002 delivers increased accuracy and faster performance to a much broader
 range of systems.  Mopac 2002 includes:
 * The PM5 method, which is 4 times more accurate than PM3 and AM1
 * AM1-d parameters for the following transition metals:
     Ti, V, Fe, Cu, Mo, Pd, Ag, and Pt
 * All main-group elements and Zn, Cd, and Hg are available for
     MNDO, AM1, PM3 and PM5
 * Option to use external PM3(tm) parameter sets
 * Linear scaling for COSMO, which facilitates solvation for large systems
     Solvent phase takes only 25% longer than gas-phase
 * More accurate and robust COSMO surface construction
 * Improved convergence in MOZYME through level shifting
 * Improved eigenvector evaluation increases speed and decreases memory
     requirements
 The advanced features of Mopac 2002 are also available on Windows and Macintosh
 in the CAChe package. Please visit http://www.schrodinger.com or contact

 site also has a full comparison, by element, of the PM5 method to other
 semiempirical parameter sets.
