## Abstract A variety of protonated dipeptides and tripeptides containing glutamic acid or glutamine were prepared by electrospray ionization or by fast atom bombardment ionization and their fragmentation pathways elucidated using metastable ion studies, energyβresolved mass spectrometry and triple

The metastable ion fragmentation reactions of protonated a-amino acids were recorded. In addition, the lowenergy collision-induced dissociation (CID) reactions were studied as a function of collision energy and breakdown graphs, expressing the energy dependence of the fragmentation reactions, were e
## Abstract Methods for the semitechnical preparation of pure thioacetic acid from hydrogen sulphide and acetic anhydride are described. An output of lb./hr. was obtained from a batch process and J lb./hr. from a continuous process using hydrogen sulphide generated from hydrochloric acid and sodium
