Abstract
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 (1 S) photofragment via the S (3 D ° 1–1 S) transition. The PHOFEX spectrum near 154 nm is better resolved than previous absorption spectra, and new features are visible. The LIFspectrum of the S (1 S) photofragment may be successfully modeled using the product recoil anisotropy (β=1.8±0.2) and CO (v,J) product state distribution previously measured for photodissociation of OCS at 157 nm [Strauss et al., J. Chem. Phys. 90, 5364 (1989)].Keywords
