Comparison of reagent stretch vs bend excitation in the hydrogen atom + water-d2 reaction: an example of mode-selective chemistry

摘要: A state-to-state study of the reaction H+D 2 O(υ 1 ,υ 3 )→OD(υ,N)+HD was carried out to compare effects reagent stretch and bend excitation. D O prepared by infrared excitation in either asymmetric fundamental state, denoted O(0,0,1), or bend-asymmetric combination O(0,1,1). Fast H atoms are generated photolysis H1 at 266 nm, OD product is quantumstate-specifically laser-induced fluorescence.
