Abstract

The open-shell van der Waals complexes OH/D-Rg (Rg = Ne, Ar, Kr) have attracted much experimental and theoretical attention during the past few years. These complexes are easily detected and small enough for rigorous theoretical treatment. Large differences in the intermolecular potential energy surfaces for the ground (X²∏) and electronically excited (A²∑⁺) states permit the observation of progressions of intermolecular vibrational modes. Potential energy surfaces have been derived from analyses of the ro-vibronic level structures. Dissociation energies of the OH/D(A)-Rg bonds were found to be 160 (Ne), 1062 (Ar), and 1840 (Kr) cm⁻¹.
