Abstract:

The recent achievements in the photo-excitation and photo-dissociation dynamics research on the triatomic molecular ions (CS+2, SO+2, CO+2) are reviewed. The parent ions with selected vibrational states are prepared via resonance-enhanced multiphoton ionization (REMPI) of neutral molecules by using an ionization laser, and then the photo-dissociation spectra (the depletion spectra of the parent ions and the enhanced spectra of fragment ions) are obtained by using another one or two dissociation lasers overlapped temporally and spatially with the ionization laser. Based on photo-dissociation spectra the photo-excitation and the photo-dissociation dynamics of CS+2, SO+2, CO+2 are investigated.

Key words: CS+2, SO+2, CO+2, REMPI, photo-dissociation spectrum
