Photodissociation dynamics of H2S+ via <i>A</i>2<i>A</i>1 (0, 11, 0) state
Time-sliced velocity map ion imaging (VMI) experiments were performed to investigate the photodissociation of H2S+X2B1, via the excitation to the A2A1 (0, 11, 0) state. Experimental images of the S+ (4Su) products were recorded near 349.60 nm for the K = 1 band, and near 344.30 nm for the K = 2 band. The derived product total kinetic energy release (TKER) spectra exhibit partially rotationally resolved structures corresponding to the H2(X1Σg+) co-products. The observed product state and angular distributions both exhibit sensitive dependence on the photolysis wavelength at near 349.60 nm and 344.30 nm. These phenomena indicate the underlying rich dynamic details and the role of the rotational excitation of H2S+.
