Overview

Implements the forcefield terms and parameters from OPLS-AA (2005 version) as found in:

  • W. L. Jorgensen, D. S. Maxwell, and J. Tirado-Rives, J. Am. Chem. Soc. 118, 11225-11236 (1996).
  • W. L. Jorgensen and N. A. McDonald, Theochem 424, 145-155 (1998).
  • W. L. Jorgensen and N. A. McDonald, J. Phys. Chem. B 102, 8049-8059 (1998).
  • R. C. Rizzo and W. L. Jorgensen, J. Am. Chem. Soc. 121, 4827-4836 (1999).
  • M. L. Price, D. Ostrovsky, and W. L. Jorgensen, J. Comp. Chem. 22, 1340-1352, (2001).
  • E. K. Watkins and W. L. Jorgensen, J. Phys. Chem. A 105, 4118-4125 (2001).

Automatic type detection is implemented only for specific subsections of the forcefield, each contained within their own “satellite” forcefield as listed above.

Implementation Notes

Atom Types

  • Epsilon values have been converted from kcal to kJ.
  • Atom types containing ‘’ (e.g. ‘C’, ‘N*’) are renamed to use ‘^’ as ‘*’ represents a wildcard match in the name.
