ANALYSIS OF ROTATIONALLY COOLED VIBRONIC EMISSION-SPECTRA (1(2)A(2)-]1(2)B(2)) OF M-XYLYL RADICAL

The rotationally cooled but electronically excited m-xylyl radical has been generated in a jet from the gas mixture of precursor m-xylene an d buffer gas He by a technique of corona excited supersonic expansion. The visible vibronic emission spectra in the transition of 1(2)A(2)-- >1(2)B(2) of m-xylyl radical in the gas phase have been recorded using a Fourier transform spectrometer. The spectra have been analyzed for the assignments of the vibrational frequencies in the electronic groun d state with combination of the torsional frequencies reported previou sly.
