HIGH RESOLUTION SPECTROSCOPY OF BENZYL AND RELATED RADICALS

Abstract

Rotationally resolved LIF electronic spectra of jet cooled benzyl radical have been recorded for the type-A $A^{1}$ and type-B $6a^{1}_{0}$ bands. Calibrated band frequencies, ground state and excited state rotational constants have been well determined. Results confirm and extend earlier contour analysis of spectra obtained with absorption $techniques.^{1}$ Recent results from other aryl-substituted radicals will also be presented.
