โœฆ Synopsis

Cbemical ionization mpss spectra of halomethanes measured using tetramethylsiiaw as reagent gas exhibit three major peaks corresponding to [ M + SiMe,l*, IM -XI + and (MeSi)lX+ ions (X = C1, Br or I). Dihalomethaws CH,X, form tbe most stable silylated molecular iom, whereas in the mass spectra of tetrahalomethanes (CX,) tbese ions have m t been detected and the ions CX3+ are the most abundant. Production of bistrimethylsiiylhalonium iws is tbe most promuaced process for haloforms (CHX,).

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

The tetramethylsilane (TMS) chemical ionization (CI) mass spectra of some geometrical isomers of unsaturated dicarboxylic acids, esters and isomeric phthalic acids reveal explicit differences. The (@-acids show an abundant [ M + 73 -CH,I + ion whereas the (a-acids exhibit a strong [ M + 73 -H,OJ + i
