“…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.…”

The Cr + -D 2 cation complex: Accurate experimental dissociation energy, intermolecular bond length, and vibrational parametersThe dissociation dynamics of HeI 35 Cl (B,v ′ =2,3) complexes with varying amounts of internal energy J. Chem. Phys. 122, 044318 (2005); 10.1063/1.1829971Rovibrational and dynamical properties of the hydrogen bonded complex ( CH 2 ) 2 S-HF : A combined free jet, cell, and neon matrix-Fourier transform infrared study Photofragment final state distributions have been measured for the vibrational predissociation of CO 2 -HF corresponding to excitation of the H-F stretching vibration. The method used in these studies combines photofragment translational spectroscopy, pendular state orientation methods, and laser probing to provide distributions that include the interfragment state correlations. The results clearly show that the dominant dissociation channel involves intermolecular V -V energy transfer corresponding primarily to excitation of the asymmetric stretching vibration of the CO 2 fragment. The dissociation energy of the complex has also been determined to be 672Ϯ4 cm Ϫ1 .

“…Examples of the use of fluorescence spectroscopy as a probe of vibronic level population dynamics include the determination of propensity rules for vibrational energy relaxation from a single vibronic level due to collisions17"20 and to vibrational predissociation of van der Waals complexes. 21 Relative cross sections of the various level-to-level relaxation pathways are measured in these steady-state experiments.…”
