The chemical ionization mass spectra of polyamines have been used to determine the importance of competing intramolecular reactions of protonated molecules in the gas phase. Multifunctional molecules react if possible in the order of intramolecular displacement-cyclization reactions, stabilization o

## Abstract HโD exchange reactions of methanolโ__d__~1~ with protonated amino acids were performed in an externalโsource Fourier transform mass spectrometer. Absolute rate constants were determined for the group which included glycine, alanine, valine, leucine, isoleucine and proline. By comparing
The gas-phase H-D exchange reactions of protonated amino acids and small peptides with ND, have been studied for reactions occurring in the quadruple collision cell of a hybrid BEqQ mass spectrometer (B = magnetic sector, E = electric sector, q = quadrupole collision cell, Q = quadrupole mass analyz
