“…Near-infrared methods [4][5][6] have been used to study vibrational predissociation on the ground electronic surface, while vibronic spectroscopy provides access to similar processes in electronically excited states. [8][9][10][11][12] Until recently, studies providing information of the photofragment final state distributions were primarily limited to studies involving electronic excitation, such as s-tetrazine-Ar, 8 benzene-He, Ar, 9 glyoxal-H 2 , D 2 , Ar, Kr, 10,11 and pyrimidine-Ar, N 2 . 12 In all of these studies, the fragment vibrational distributions were found to be highly nonstatistical, such that only a small subset of the available vibrational states was populated.…”
