New ab initio studies of the OH(A (2)Sigma(+))-Ar system reveal significantly deeper potential energy wells than previously believed, particularly for the linear configuration in which Ar is bound to the oxygen atom side of OH(A (2)Sigma(+)). In spite of this difference with previous ab initio work, bound state calculations based on a new RCCSD(T) potential energy surface yield an energy level structure in reasonable accord with previous theoretical and experimental studies. Preliminary open ...Expand abstract
