The proposed research will explore photoinitiated chemical reaction dynamics from a weakly-bound complex containing mutually reactive species. The experimental approach will be to photolytically generate a van der Waals complex of reactants in a supersonic expansion and to activate monomer vibrations via infrared excitation to initiate a chemical reaction. Reaction systems of particular interest are those involving the transfer of a light hydrogen atom between two heavy atom partners,X + HY a XH + Y (where X and Y are Cl, Br, or O). Excitation of the HY monomer vibration of reactive X-HY complexes will be achieved using the output of an external cavity diode laser operating in the near infrared coupled to a cavity ring-down (CRD) spectrometer. In addition to activation of the HY intramolecular vibration, it will also be possible to simultaneously excite combination bands involving internal bending motion of the complex. The narrow bandwidth afforded by the diode laser will be sufficient to resolve rotational structure in the infrared spectrum and determine any homogeneous linebroadening associated with reactive and inelastic scattering dynamics of the vibrationaly excited X-HY complexes.A systematic analysis of the variation of lifetime broadening of spectral lines within vibrationsl bands associated with intermolecular bending and stretching excitation will allow inferences to be made on how the initial orientation of the reactants influences the dissociation dynamics.
