The proposed research aims to investigate the infrared spectroscopy and photoinitiated dynamics of chemical reactants stabilised in weakly-bound clusters using a novel experimental approach. The experimental procedure will be to photolytically generate reactant complexes within a supersonic slit jet expansion and to probe their infrared spectroscopy and vibrationally excited dynamics using a high-resolution diode laser cavity ring-down spectrometer. Reaction systems of particular interest are those involving the transfer of a light hydrogen atom between two heavy atom partners, X + HY -> XH + Y (where X and Y are F or C1). The infrared spectroscopy of X-HY reactant complexes will provide a sensitive probe of the topology of the relevant reactive potential energy surfaces. In addition, the spectrum will contain information regarding the vibrationally excited dynamics of the reactant complexes. Excitation of the HY bond of the reactant complexes places sufficient energy into the system to initiate both reactive and inelastic scattering events, these effects will be manifest in the spectrum as splittings and lifetime broadening within the rotational fine structure. Furthermore, steric aspects of the dynamics will be investigated by varying the initial geometry of the reactants by simultaneous excitation of the HY stretch and intermolecular bending motion.
