INITIAL STATE-SELECTED REACTION PROBABILITIES FOR OH-2-]H+H2O AND PHOTODETACHMENT INTENSITIES FOR HOH2-(H)

We have used a discrete variable representation (DVR) with absorbing b oundary conditions (ABC) to calculate initial state-selected reaction probabilities and photodetachment intensities. We apply this method to the OH+H-2 reaction constrained to a plane with the OH bond frozen. T he calculated reaction probabilities have all the qualitative features observed in full dimensional calculations. We have similarly computed arrangement-selected photodetachment intensities for one geometry of the HOH2- anion. The resulting spectrum has a dominant peak which will present a test of the neutral potential energy surface upon compariso n with experimental results.
