# EROTVIB, a general program to calculate rotationally and / or vibrationally elastic and inelastic cross sections for electron (positron) scattering by spherical, symmetric and asymmetric top molecules

## Description

Title of program: EROTVIB Catalogue Id: AAJM_v1_0 Nature of problem This program calculates cross sections (total, differential and momentum transfer) for rotationally and/or vibrationally elastic and inelastic scattering of low energy electron (positron) impact by polyatomic molecules. It requires the body-fixed (BF) frame K-matrices for each symmetry (and at each geometry in case of vibrational excitation) as the input. For a polar molecule, the program has the provision to use the closure formula of Crawford and Dalgarno in order to obtain converged cross sec ...
