Times Cited Count:21 Percentile:57.15(Chemistry, Physical)Vibrationally excited HOD in the fourth overtone state of the OD-stretching mode (5) has been photodissociated by ultraviolet photolysis at ca. 243.1 nm. Branching ratio between the OH- and OD-bond dissociation channels has been determined by detecting the H and D atoms. The OD-bond dissociation is the dominant channel, with the yield of H atom generated by the photolysis being below the detection limit.

We explored the pulse shape to excite the vibrational states of diatomic molecules whose rotational states were excited isotope-selectively by a terahertz pulse train. Computer simulations based on the coupled-channel method were performed using the gaseous LiCl and LiCl ensembles in 70 K. The isotope-selective vibrational excitation was investigated using the pulse which has a quasi-rectangle or the Gaussian spectrum. The results indicated that the isotope-selective vibrational excitation can be induced effectively by specifying the spectral frequency range referring to the transition frequencies in the P- and R-branches of molecules. The P-branch transition plays an important role on the excitation in low vibrational states, and both the P- and R-branch transitions contribute to the excitation in high vibrational states.
