Abstract

Dissociation of the OCS monomer at 222 nm yields S(¹D) and S(³P) in the ratio 0.85/0.15 and CO which is >98% in v = 0 but with very high rotational energy. The peak in the rotational distribution occurs at J = 55 and corresponds to about 56% of the available energy for the S(¹D) channel. These results support the contention that the upper OCS 1Δ state is bent. Dissociation of OCS clusters leads to a completely different photochemistry: at least some of the CO is formed rotationally cold (T_rot ≃ 50 K), and S₂ is also produced.
