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
## Abstract HβD exchange reactions of methanolβ__d__~1~ with protonated amino acids were performed in an externalβsource Fourier transform mass spectrometer. Absolute rate constants were determined for the group which included glycine, alanine, valine, leucine, isoleucine and proline. By comparing
