英文摘要 | Photodissociation dynamics of n-C7H15Br molecule was investigated at different wavelengths of 231 to 239 run by an ion imaging spectrometer operated under optimal conditions for velocity mapping, where the ions were generated from (2+1) resonance enhanced ionization (REMPI) of the photofragments Br(P-2(3/2)) and Br*(P-2(1/2)) at the same wavelength as that of the photolysis laser. The released kinetic energies and the angular distributions of both fragments at different photolysis wavelengths were derived from the three-dimensional velocity images. The probabilities of the individual pathways of the fragments at 234 nm were calculated from the relative quantum yield and angular distribution. The total translational energy distributions were interpreted using soft impulsive model. The anisotropy parameter for Br* is sensitive to the photolysis wavelength. This fact can be explained by the adiabatic and non-adiabatic dissociation processes in the electronically excited states of n-C7H15Br. |
