Infrared Multiphoton Dissociation of the Nitrobenzene Cation.
Abstract
Infrared multiphoton dissociation (IRMPD) of nitrobenzene cations has been shown to proceed via three pathways of ca. 1-2 eV activation energy to produce C6H5, C5H5, and NO ions. Observation of these three fragment ions and not C6H5, which has approximately the same appearance energy, suggests that they are produced from high vibrational levels of the ground electronic state of the cation, while the C6H5 either has a higher appearance energy than previously reported or is produced by dissociation from an isolated electronic state. To explain all aspects of the observed formation of C5H5 and C6H5O fragment ions from nitrobenzene cations by IRMPD two different dissociation pathways leading to C6H5O ions and one leads tro unstable C6H5O which further dissociates to C5H5.
