Mass Resolved Excitation Spectroscopy of Benzyl and Phenylnitrene Radicals

Abstract

Two-color mass resolved excitation spectra are obtained for the benzyl and phenylnitrene radicals. The spectrum previously assigned to the benzyl radical is generated by a species with mass 91 amu. This finding is consistent with the proposed benzyl radical structure. The origin of transition lies at 21,997 cm-1. The ionization energy for the benzyl radical is ca. 7.236 eV. The phenylnitrene radical spectrum is associated with a species of 90 amu. The phenylnitrene designation is not appropriate for this mass number: the suggested cyanocyclopentadienyl radical species (C5H4 CN) is consistent with this mass. This radical has an ionization threshold of ca. 9.05 eV. Lifetimes are reported for a number of the vibronic states of both radicals.
