The photodissociation cross section of the weakly bound positive ion clustur Ot(H;?O) has been measured at I5 discrete energes between 1.833 and 2.727 eV. Measurements indicate the cross section increases smoothly from 0.6 to 6 x lo-" cm2 over this eriergy range. These cross section values are the l

โฆ Synopsis
We have performed calculations for the photodissociation of HzS using surfaces constructed to test a model proposed by van Veen et al., in which the dissociation occcrs via predissociated levels of the bound * B1 excited state. Total Franck-Condon factors for the photodissociation and partial Franck-Condon factors for the product vibrational distributions are presented.

Photodissociation of HrS in krypton matrices is followed by monitoring laser-induced fluorescence from the SH photofragment. No evidence of an energy threshold for dissociation is observed. Quantum yields of dissociation, referenced to gas-phase absorption cross sections, increase nearly linearly fr
The momentum spectrum of H\* ions obtained by photodissociation of a H': beam with a laser has been measured. The relative distribution over several vibrational levels in the primary beam is calculated.
Photodissociation of H$ has been studied at 193.3 nm using H atom photofragment-translational speclroscopy with massspectrometric detection. H t HS( v) product branching ratios are reported which are not in quantitative agreement with other recent experimental results. Secondary photodissociation of
Mg+-H20 ion-molecule complexes are produced in a pulsed supersonic nozzle cluster source. These weakly bound complexes are mass selected and studied with laser photodissociation spectroscopy in a reflectron time-of-flight mass spectrometer system. An electronic transition assigned as 2B2--}X 2A1 is
