Description

Title:The Three-dimensional Potential Energy Surface Of Ar-co
Author(s):Sumiyoshi, Yoshihiro
Contributor(s):Endo, Yasuki
Subject(s):Theory and Computation
Abstract:A three-dimensional intermolecular potential energy surface of the Ar-CO complex has been determined by utilizing previously reported spectroscopic data, where 971 transition frequencies by microwave, millimeter-wave, submillimeter-wave, and IR spectroscopy were reproduced simultaneously within experimental accuracies. A free rotor model Hamiltonian considering all the freedom of motions for an atom-diatom system was used to calculate vibration-rotation energies. The three-dimensional potential energy surface by {\it ab initio} calculations at the CCSD(T)-F12b/aug-cc-pV5Z level of theory were parameterized by a model function consisting of 46 potential parameters and they were used as initial values in the least-squares analysis. In total 20 potential parameters were optimized to reproduce all the experimental data.
