A new, fully ab initio investigation of the ArNO(X 2Π) system. II. Bound states of the Ar–NO complex

We report an investigation of bound states of the ArNO complex, based on new coupled-cluster [CCSD(T)] ab initio potential energy surfaces. The position and relative spacing of the lowest bend–stretch levels of the complex are found to be in noticeable better agreement with available experimental results than the predictions based on earlier ArNO PES’s.
