摘要：

Results are presented on the ultraviolet photolysis of H2Se. An experimental approach is introduced that combines velocity-aligned Doppler spectroscopy (VADS) with time-of-flight (TOF) methods. Atomic hydrogen is detected, and by utilizing a tunable photolysis source, one is able to map out propensities for populating HSe vibrational states as a function of photolysis wavelength. Interest in observing such behavior in triatomic systems was suggested theoretically by Schinke and co-workers in the mid-1980s.
