Laser Induced Fluorescence of ClO2

Abstract

Fluorescence spectra of the A(2A2)–X(2B1) system of ClO2 excited by five visible Ar-ion laser lines (4579–4880 Å) have been observed over a wavelength region from near excitation to beyond 7000 Å. Approximately 60 fluorescence bands have been observed for each laser line excitation and about half of these bands have been assigned. Vibrational constants of the ground state have been calculated from observed band positions.
