Abstract
The major fragmentations of isomeric dimethylphenoxide anions upon col lisional activation are losses of H . and Me .. Two minor processes in volve the formation of m/z 79 (C6H7-) (-C2H2O) and m/z 77 (C6H5-) [-(M e . + CHO .)]. The former is only observed when (at least) one of the ortho carbons bears a hydrogen substituent, the latter only when there is a 4-methyl substituent. (C) 1997 John Wiley & Sons, Ltd.
