The characteristic coUisionLinduced dissociations of (M -HI-ions of dipeptides and tripeptides involve proton transfer to the carboxylate centre as a prelude to fragmentation. Dipeptides show the process + NH,C(R')=C=O (R = H or alkyl) while tripeptides show the analogous processes NH,CH(R')CONHCH(R

## Abstract The collision‐induced dissociation (CID) fragmentation reactions of a variety of deprotonated peptides containing proline have been studied in detail using MS^2^ and MS^3^ experiments, deuterium labelling and accurate mass measurements when necessary.
