Description

A new high quality potential energy surface for the He-OCS van der Waals complex was calculated using the CCSD(T) method and avqz+33221 basis set. It is found that the global minimum energy is −51.33 cm−1 at Re = 6.30a0 and θe = 110.0°, the shallower minimum is located at R = 8.50a0 and θ = 0° with well depth −32.26 cm−1. Using the fitted potential energy surface, we have calculated bound energy levels of the He-OCS, He-O13CS, He-OC34S, and 3He-OCS complexes. The theoretical results are all in better agreement compared to previous theoretical work
