Photodissociation dynamics of H2S+ near 325 nm
|Corresponding Author||Yuan，Daofu; Wang，Xingan|
We study the photodissociation dynamics of the hydrogen sulfide cations (HS) using the time-sliced velocity map ion imaging (VMI) technique and high-accuracy calculations. High-resolution ion images of the S(S) products were measured at four photolysis wavelengths of 325.158, 325.200, 325.243, 325.307 nm, which correspond to the excitation to the AA(0,13,0) K=1 state of HS. Rotational state-resolved total kinetic energy releases and angular distributions have been derived as a function of the photolysis wavelengths. Notably, photolysis wavelength dependent product rotational state and anisotropy parameter distributions have been clearly observed. Full-dimensional potential energy surface characterization suggests that nonadiabatic coupling between AA and BB states at C configurations, as well as relaxation of the symmetry to C in the conical intersection region between the two states, plays a key role in the photodissociation process.
