Initial state-selected reaction probabilities for OH+H2→H+H2O and photodetachment intensities for HOH−2

We have used a discrete variable representation (DVR) with absorbing boundary conditions (ABC) to calculate initial state-selected reaction probabilities and photodetachment intensities. We apply this method to the OH+H2 reaction constrained to a plane with the OH bond frozen. The 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 HOH−2 anion. The resulting spectrum has a dominant peak which will present a test of the neutral potential energy surface upon comparison with experimental results.
