We have built the spectrometer for obtaining a high resolution enission spectra of unstable species in the visible and u.v. range. For the spectrometer, a high resolution Fourier transform spectrometer (Bruker IFS-120HR) or a 1.0-m path length of monochromator has been employed with a PMT detector. The unstable species was generated in a Jet by an electric DC discharge in a supersonic expansion chamber made by a Pyrex glass tube. With this facility, we have obtained the high resolution emission spectra of benzyl and xylyl radicals generated from toluene and xylenes, respectively. The spectra show good S/N and the rotational temperature is high enough to see the rotational contours of the bands.
