Abstract

Ionization and fragmentation of the amino acid glycine upon interaction with He2+ ions has been studied. By means of time-of-flight spectroscopy the fragments have been analyzed. Goal was to identify temperatures at which the glycine molecule vaporizes without being thermally dissociated. It was found that in the region of 145 °C to 180 °C the glycine molecule vaporizes without thermal dissociation. Future measurements are recommended to be done at temperatures between 160 °C and 180 °C. A fragment coincidence measurement has also been performed. This showed coincidence of fragments such as H+, CH+, N+, NH4 + HCNH+, NH2CH2 +, HOCO+ and others. Insufficient statistics allowed only one kinetic energy release (KER) estimation to be made, which was found at 6.3 μeV and too small to be correct.
