Tunable Vacuum-Ultraviolet Photofragment Excitation Spectroscopy of OCS
Photofragment excitation (PHOFEX) spectroscopy of OCS in the vacuum ultraviolet (VUV) has been carried out using tunable VUV excitation of jet-cooled OCS, followed by ultraviolet laser induced fluorescence (LIF) detection of the S (S-1) photofragment via the S (D-3(1)-S-1) transition. The PHOFEX spectrum near 154 nm is better resolved than previous absorption spectra, and new features are visible. The LIF spectrum of the S (S-1) photofragment may be successfully modeled using the product recoil anisotropy (beta=1.8+/-0.2) and CO (upsilon,J) product state distribution previously measured for photodissociation of OCS at 157 nm [Strauss et al., J. Chem. Phys. 90, 5364 (1989)].
