Title

Electronic spectroscopy of the OH–CO reactant complex

Abstract

A broad and relatively unstructured electronic excitation spectrum has been observed for the OH–CO reactant complex in the OH A–X (1,0) region by laser-induced fluorescence and fluorescence depletion methods. The electronic spectrum spans from 33 500 to 36050 cm -1 and peaks near 34600 cm -1. Fluorescence depletion methods have been employed to demonstrate that the broad electronic spectrum originates from the same linear, hydrogen-bonded OH–CO complex that gives rise to a rotationally resolved infrared spectrum. The electronic spectrum is consistent with a Franck–Condon mapping of the ground state radial distribution on a strongly attractive excited state potential that undergoes rapid decay dynamics.
