 Title: THE ROLE OF HIGHER-MULTIPOLAR AND REPULSIVE FORCES IN THE CALCULATION OF COLLISION-BROADENED LINE-WIDTHS OF LINEAR MOLECULES Creators: Varanasi, P.; Sarangi, Sunil Issue Date: 1974 Publisher: Ohio State University Abstract: Collision-broadened line widths in $CO - CO_{2}$ and $CO - O_{2}$ collisions have been calculated by incorporating interactions due to octopoles and hexadecapoles and short range repulsive interactions into Anderson’s theory. It is shown how these higher-order interactions can be manipulated to yield good agreement with experimental data. A critical evaluation of this totally empirical manipulation suggests that a thorough revision of the theory is required for all but simple dipole-dipole interactions. In the process of the evaluation, the values of the multipole moments are discussed. This research was supported by NASA under Grant No. NGR-33-OL5-139.
