摘要: Coupled cluster quantum chemical calculations of the potential energy surface and induced dipole are reported for He-Ar van der Waals collisional complex. Spectroscopic parameters derived from global analytical fits while an accurate value long-range coefficient D7 is obtained by perturbation methods. Collision-induced absorption spectra computed mechanically compared with existing measurements.
