Coherent Anti-Stokes Raman Scattering (CARS) Detection or Hot Atom Reaction Product Internal Energy Distributions.

摘要

Coherent anti-Stokes Raman spectroscopy (CARS) is being utilized to investigate the rovibrational energy distributions produced by reactive and nonreactive collisions of translationally hot atoms with simple molecules. Translationally hot H atoms are produced by ArF laser photolysis of HBr. Using CARS we have monitored, in a state-specific and time-resolved manner, rotational excitation of HBr (v = 0), vibrational excitation of HBr and H sub 2 , rovibrational excitation of H sub 2 produced by the reaction H + HBr implies H sub 2 + Br, and Br atom production by photolysis of HBr.
