Slow ion interaction with N-methylglycine and N-acetylglycine

N-acetyl glycine and N-methyl glycine molecules in the gas phase are ionized by electron exchange with slow O6+ ions at an energy of 48 keV. After ionization, the methyl and acetyl substituted glycines dissociate into fragments analogous to that resulting from ionization and fragmentation of amino a...

Sumario:N-acetyl glycine and N-methyl glycine molecules in the gas phase are ionized by electron exchange with slow O6+ ions at an energy of 48 keV. After ionization, the methyl and acetyl substituted glycines dissociate into fragments analogous to that resulting from ionization and fragmentation of amino acids and peptides, respectively. N-acetylglycine which contains a peptide bond also effectively tautomerizes to the diol form. Such tautomerization is typical for amino acids, however, we show that the tautomerization mechanism of the N-acetylglycine is different
