Abstract The TRIATOM program suite calculates energy levels, wavefunctions, and where appropriate, dipole transition moments and spectra, for rotating and vibrating triatomic molecules. Potential energy, and where necessary, dipole surfaces must be provided. The programs use an exact (within the Born-Oppenheimer approximation) Hamiltonian, offer a choice of several body-fixed, internal coordinate systems based on two distances and an included angle and employ basis function expansions of orthogonal po... Title of program: ROTLEVD Catalogue Id: ABJY_v2_0 [ACLZ] Nature of problem ROTLEVD performs the second step in a two-step variational calculation for the bound ro-vibrational levels of a triatomic system [1].
