Notes:
Low resolution mass spectrometric studies were carried out on biphenyl, the 2-, 3- and 4-methyl substituted biphenyls, the 2,2′-, 2,3′-, 2,4′-, 3,3′-, 3,4′- and 4,4′- dimethyl substituted biphenyls, in addition to diduryl. Number and position of the methyl substituent have a marked effect on the observed fragmentation. In biphenyl and the monomethyl series [M - 1] is a major fragment whereas in the dimethyl series and diduryl the [M - 15] represents a significant ion species. A methyl located in the ortho position results in the greatest influence on the cracking pattern. Potential mechanisms are discussed.
