Internal and translational energy partitioning of the NO product in the S-2 photodissociation of methyl nitrite
State-resolved scattering distributions of the NO product in the photodissociation of CH3O-NO were measured at 213 nm with resonantly-enhanced multiphoton ionization spectroscopy and ion-imaging. The spectra of the NO product displayed the vibrational population up to the v=3 state having the rotational state-distribution with a Gaussian-like function. The scattering data of the NO (v=1) product indicate that the rotational excitation of the NO fragment and the translational energy release are fairly well compensated. This result is explained as being an outcome of the strong repulsion in the CH3O-NO bond in the S-2 state. (C) 2017 Elsevier B.V. All rights reserved.
