Photodissociation Dynamics of H2S+via A2A1(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 im-ages 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 struc-tures corresponding to the H2(X1∑g+)co-products.The observed product state and angular distributions both ex-hibit 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+.
