A program suite for the calculation of ro-vibrational spectra of triatomic molecules
Description
Abstract A program suite for the calculation of ro-vibrational eigenfunctions of triatomic molecules is presented. The suite enables first principles calculations - starting from a set of basis functions and electronic potential energy and dipole surfaces - of the energy levels, transition frequencies and synthetic stick spectra to be made. The suite is based around the main driver program TRIATOM. This has been improved, to make more efficient use of vector processors and available memory, and genera... Title of program: ROTLEVD Catalogue Id: ABJY_v1_0 Nature of problem ROTLEVD performs the second step in a two-step variational calculation for the bound ro-vibrational levels of a triatomic system.
