Anharmonic vibrational properties by a fully automated second-order perturbative approach

J Chem Phys. 2005 Jan 1;122(1):14108. doi: 10.1063/1.1824881.

Abstract

This paper describes the implementation of a fully automated code for the building of anharmonic force constants and their use in a second-order perturbative evaluation of vibrorotational parameters. Next, a number of test applications are discussed, which show the strengths and limits of various computational levels.
