Abstract:
We study the photodissociation dynamics of CS2 in the ultraviolet region using the time-sliced velocity map ion imaging technique. The S(3PJ)+CS(X1Σ+) product channels were observed and identified at four wavelengths of 201.36, 203.10, 204.85 and 206.61 nm. In the measured images of S(3PJ=2,1,0), the vibrational states of the CS(X1Σ+) co-products were partially resolved and the vibrational state distributions were determined. Moreover, the product total kinetic energy releases and the anisotropic parameters were derived. The relatively small anisotropic parameter values indicate that the S(3PJ=2,1,0)+CS(X1Σ+) channels are very likely formed via the indirect predissociation process of CS2. The study of the S(3PJ=2,1,0)+CS(X1Σ+) channels, which come from the spin-orbit coupling dissociation process of CS2, shows that nonadiabatic process plays a role in the ultraviolet photodissociation of CS2.
