ROTATIONALLY INELASTIC AND BOUND-STATE DYNAMICS OF H-2-OH(X(2)PI)

Rotationally inelastic scattering cross-sections and van der Waals rovibrational spectra of the H-2-OH system are calculated using two ab initio potential surfaces. The scattering calculations give similar results when both ab initio potentials are used, and show quite good agreement with available experimental data. The van der Waals bound states and rovibrational spectra show interesting similarities and differences when compared with the related and well studied Ar-OH and H-2-HF systems. Aspects of the spectra calculated using two ab initio potentials show marked differences, and suggest that experimental studies of the far infrared or near infrared spectra of H-2-OH will be worthwhile.
