State‐to‐state dissociation of OClO(Ã 2A2ν1,0,0)→ClO(X 2ΠΩ,v, J)+O(3P)

摘要: Applying the two‐photon laser‐induced fluorescence technique for nascent state resolved ClO(X 2ΠΩ,v,J) detection, photofragmentation dynamics of OClO in (A 2A211,0,0) and (A 2A218,0,0) is investigated at fixed photolysis wavelengths 351 nm 308 nm. In both experiments product fragments are formed their electronic ground states, namely ClO(2ΠΩ) O(3P). A complete analysis proves ClO radicals originating from OClO(A 2A211,0,0) dissociation to be v=0–4 vibrational states with a spin–orbit ratio P(2Π3/2):P(2Π1/2)=3.8±0.5. The fragment shows moderate rotational excitation. obtained distributions relatively high translational energy can explained by predissociation (A 2A2ν1,0,0)‐excited parent molecule course which initial symmetric stretch motion (ν1) transferred into dissociative asymmetric stretching mode (ν3). line profile measuremen...
