Chemical ionization of chloromethanes for matrix isolation spectroscopy

Hacaloğlu, Jale
Andrews, Lester
A chemical ionization source from mass spectrometry has been used with CCl4, CHCl3 and CH2Cl2/argon mixtures for matrix isolation spectroscopy in the IR and visible-near UV regions. The major product absorptions in both regions have been observed and assigned previously. The comparison of positive and negative ion operation is striking for CCl4; the yields of CCl+3, CCl+4 and Cl+3 are increased and HCl−2 is not produced in positive ion operation.
