英文摘要 | photodissociation dynamics of c2h5sh, i-c-3-h7sh and n-c3h7sh at 243.1 nm were investigated using velocity map ion-imaging method. h-atom photolysis products were detected by a (2 + 1) resonance enhanced ionization scheme. both the angular distribution and translational energy distribution of the h-atom elimination processes were determined from the ion images of the h-atom products. the experimental results indicate that the h-atom eliminations from these molecules are mainly direct and fast dissociation processes from a repulsive potential energy state. and a more statistical dissociation process that likely occurs oil the ground state via internal conversion has also been observed. dissociation energies of the s-h bonds are also derived from the h-atom product translational energy distributions.
