The tetramethylsilane (TMS) chemical ionization (CI) spectra of the mono-substituted aromatics studied contain M+' and adduct [M + (CH, 1, IS]' ions. Abundant M+' ions are observed in compounds with electrondonating groups and are attributed to charge-exchange reactions of reactant ions in the TMS C
