Abstract

The process of fragmentation of the glycine of molecule (C2H5NO2), a compound that belongs to the series of amino acids, has been studied using crossed electron and molecular beams and mass-spectrometric analysis. Primary attention is focused on the formation of charged fragments of the initial molecule as a result of both the direct impact of low-energy electrons (dissociative ionization) and the thermal degradation of glycine on heating followed by the electron-impact ionization. The mass-spectrometric analysis of molecular fragments was performed using a commercial magnetic mass spectrometer of the MI-1201 type, the construction of which was subjected to significant improvement.
