Spectroscopic studies of a molecular beam bombarded by a low energy electron beam were carried out for several simple organic molecules. The collision chamber resembled the ionization chamber of a mass spectrometer, and the electrons were accelerated at about 270 V. The spectrum of methane showed lines of excited hydrogen atoms and bands of excited CH radicals. The spectra of chlorinated methanes showed lines of excited chlorine atoms and bands of excited hydrogen chloride positive ions (HCl<SUP>+*</SUP>) in addition. Even the spectrum of a mixture of methane and carbon tetrachloride revealed bands of HCl<SUP>+*</SUP>. Dependence of emission intensities on target currents and gas pressures indicated the origin of the excited hydrogen atoms and CH radicals to come from direct fragmentation and the excited HCl<SUP>+</SUP> ions from a bimolecular process.
