Paper Abstract

Intermolecular vibrational levels which lie above the OH (X 2$PRD) + Ar dissociation limit have been characterized by stimulated emission spectroscopy. OH-Ar complexes prepared in these levels undergo rotational or spin-orbit predissociation. The energies and lifetimes of these metastable states have been computed using a variational method and a flux projection technique. Analogous predissociative levels beyond the OH (A 2(Sigma) +) + Ar dissociation limit have been detected by laser-induced fluorescence and confirmed by hole-burning experiments. Intermolecular vibrational levels of NH-Ar have been probed in the vicinity of the NH c 1$PRD - a 1(Delta) transition, revealing information on the NH (c 1$PRD, a 1(Delta) ) + Ar interaction potentials.
