Spectroscopy Of Absorbers In Rare Gas-Halide Laser Plasmas

The spectroscopy and chemical kinetics of small molecules known (or believed) to absorb in rare gas-halide laser plasmas are being studied by laser excitation and probing tech-niques. Two examples from recent experiments -- inter-Rydberg absorption spectroscopy of Art and photoassociation (bound 4- free absorption) of Kr-F collision pairs -- are described.
