摘要: After more than forty years of scrutiny, crucial new details regarding the elementary reaction OH + CO → H CO2 are still emerging from experimental and theoretical studies HOCO radical intermediate. In this perspective, previous structure energetics will be briefly reviewed. Particular attention paid to techniques used in our laboratory prepare excited radicals by both photodetachment dissociative HOCO−. These experiments directly probe dynamics occurring on ground states radical, sensitive direct tunneling-induced dissociation. Photoelectron–photofragment coincidence HOCO− particular have been study tunneling well form products. addition, insights into entrance channel for presented. provided a number constraints potential energy surface system an energetic dynamical helped spur renewed effort characterize global fundamental chemical reaction. Outstanding questions directions future work discussed.
