AMYR 2: A new version of a computer program for pair potential calculation of molecular associations

Abstract
AMYR is a computer program for the calculation of molecular associations using Fraga's pairwise atom - atom potential. The interaction energy is evaluated through a 1/R expansion. The electrostatic energy is calculated through either the one-centre-per atom or the three-centres-per atom model by Hunter and Sanders. A pairwise dispersion energy term is included in the potential and corrected by a damping function. The program carries out energy minimizations through variable metric methods. Th...

Title of program: AMYR 2
Catalogue Id: ADIW_v1_0

Nature of problem
The program determines the optimum separation and relative orientation of two interacting molecular systems through a minimization of the interaction energy. The new version allows for two models to evaluate the electrostatic contribution: the one-centre-per atom and the three- centres-per atom models. The stationary point analysis of the intermolecular potential by means of the Hessian eigenvalues is also allowed.
