FLUORESCENCE EXCITATION SPECTRA OF JET-COOLED OXALYL HALIDES
Abstract
The fluorescence excitation spectra of jet-cooled oxalyl halides (COF)2 and (COCl)2 are measured and compared with their absorption spectra in the gas phase. High efficiency fluorescence of oxalyl fluoride molecules excited to the single vibronic levels of bg symmetry and high efficiency of nonradiative transitions for molecules excited to the single vibronic levels of αg symmetry are observed. High intensity hot band 702 801 is detected in the spectrum of oxalyl chloride. These results are compared with data for glyoxal (COH)2, obtained earlier.
