The intermolecular bending and stretching vibrations supported by the OH (X {sup 2}{Pi}) + Ar ({sup 1}S{sub 0}) potential energy surfaces have been accessed by stimulated emission pumping (SEP) of the weakly bound OH-Ar (X {sup 2}{Pi}) complex. Virtually all of the bound vibrational levels of the complex, from the zero-point level to the dissociation limit, have been identified. OH-Ar complexes prepared in these levels undergo predissociation by using OH rotational or spin-orbit excitation to break the weak OH-Ar intermolecular bond. Perturbation theory calculations have been carried out to understand the physical origin of the dynamical processes occurring on the OH (X {sup 2}{Pi}) + Ar ({sup 1}S{sub 0}) potential energy surfaces.
