Abstract
A laser‐ion beam apparatus for studying laser‐induced photodissociation and fragmentation of fast molecular ions in both coaxial and crossed beams configurations has been constructed. IR photodissociation of highly internally excited SO+2 ions is reported using a low power cw CO2 laser. The fragmentation of SO+2 into SO++O and S++O2 has been observed and the relative dissociation yields as function of laser frequency and power dependence of the two dissociation channels have been measured. No IR photodissociation could be observed for SO+ and SO+3 at 934.9 cm−1.Keywords
