## Abstract Functional group interactions and substituent effects of __o__‐, __m__‐ and __p__‐aminobenzoic acids were examined in a quadrupole ion trap by evaluation of proton‐transfer and methylene substitution reactions. An electron‐withdrawing carboxylic acid group can enhance or reduce the gas‐
The gas-phase reactions of the nitrosonium ion, NO+ with the amino acids glycine, alanine and valine and their N-methyl derivatives were investigated under chemical ionization mass spectrometric (CIMS) conditions. Two products were observed in all cases: the formation of the iminium ion and the form
## Gas -phase ion-molecule reactions of buckminsterfullerene (C 60 ) with the ion systems generated from the self-chemical ionization of alkyl methyl ethers (CH 3 OR, R = n-C 2 H 5 , n-C 3 H 7 , n-C 4 H 9 ) were studied in the ion source of a mass spectrometer. The adduct cation [C 60 C 2 H 5 O] a
The gas-phase ion-molecule reactions of the phosphonium ion formed by electron impact with OP(OCH 3 ) 2 ' neutral trimethyl phosphite were studied with the use of a quadrupole ion trap (QIT) mass spectrometer. Observed reactions include competing methoxy transfers between and the neutral species to
## Ion -molecule reactions of (acac),M' ions (M = Fe, Co) with macrocyclic thiourea derivatives (L) were studied. The formation of acacML' and acacM(L -H)' were observed. AcacM(L -H)' ions arise from loss of the hydrogen atom of the NH group. The ion peak intensity ratios, Z = (acacML' J/[acacM(L
