Gmat. A software tool for the computation of the rovibrational G matrix

Abstract
Gmat is a C++ program able to compute the rovibrational G matrix in molecules of arbitrary size. This allows the building of arbitrary rovibrational Hamiltonians. In particular, the program is designed to work with the structural results of potential energy hypersurface mappings computed in computer clusters or computational Grid environments. In the present version, 1.0, the program uses internal coordinates as vibrational coordinates, with the principal axes of inertia as body-fixed system....

Title of program: Gmat
Catalogue Id: AECZ_v1_0

Nature of problem
Computation of the rovibrational G matrix in molecules of any size. This allows the building of arbitrary rovibrational Hamiltonians. It must be possible to obtain the input data from the output files of standard electronic structure codes. In addition, the program should handle the large number of files generated in massive explorations of molecular potential energy hypersurfaces. In these cases, Gmat will provide the G matrix as a function of the molecular structure.
