Fluorescence lifetimes of NO B 'lI I,z( v' = 7) and B zH,,2(v' =7)-C -?I (v' = 0) mixed states were measured in a free jet using pulsed tunable VUV laser light. The measured lifetimes ofthe B 'II I,z state were 389 and 423 ns for J' =OS and 1.5, respectively. It was found that lifetimes of the mixed
The polarization of fluorescence from R-branch excited 08 'B, pyrimidine decays with a rate which increases with increasing J. This observation confirms the occurrence of rotation-induced K mixing, which takes place during the lifetime of the excited electronic state.
