Magnetic Resonance Spectra

Abstract Mass spectrometry allows the number of chlorine atoms per polychlorobiphenyl molecule to be determined but not the positions of substitution. A method of identifying PCB components from high resolution proton magnetic resonance spectra is illustrated by application to 2,5,2′,5′-tetrachloro- and 2,3,4,2′,4′,- 5′-hexachlorobiphenyls separated by gas chromatography from a commercial PCB mixture.

Magnetic Resonance Spectra

The high resolution proton magnetic resonance spectra of himgravine and himbacine have been obtained in CHCl3 solution at 60 Mc/s. The spectra are consistent with only one of the two possible structures proposed. Other information with regard to relative orientation of groups within the molecule has also been obtained.
