X-Ray Emission Spectra from Chlorinated Methanes and Fluorochloromethanes

The carbon $K$ , fluorine $K$ , and chlorine $L$ spectra are presented for the chlorinated methanes (CCl₄, CHCl₃, CH₂Cl₂, CH₃Cl) and fluorochloromethanes (CFCl₃, CF₂Cl₂, CF₃Cl, CHFCl₂, CHF₂Cl). Comparisons are made with the spectra of methane and carbon tetrafluoride. Multiplet structure is observed in every case. The position and intensity of the various lines is dependent on the type and number of halogens present in the molecule.
