Fluctuations in state-selected unimolecular decomposition: Double-resonance infrared visible photofragment yield spectroscopy of NO2

Abstract
Fluctuations in the NO(2Π) state distributions from the state‐selected simple bond fission unimolecular reaction of NO2 are probed using double‐resonance photofragment yield (PHOFRY) spectroscopy. These spectra are sensitive probes of the correlation of selected NO rovibronic levels with specific resonances in the excited molecule.
