Abstract

Nitric Oxide (NO) radicals, reactive intermediates found in the atmosphere, are known to be oxidized and result in acid rain and smog production. Resonant 2-Photon Ionization and Velocity Map Imaging were utilized to measure spectroscopy and dynamics of the complex formed between NO and Carbon Monoxide (CO). Data supported the possibility that the complex has 7 observable vibronic transitions and a pre-dissociative transition. Furthermore, it was observed that when undergoing dissociation, NO is produced in its excited A²Σ⁺ state, and that the time-scale of the dissociation is much faster than the rotational period of the complex.
