22-EPN3-065: Ion Bombardment of Glycine and Glycine Embedded Within Water Ice in Solar System and Interstellar Conditions

Visit by Alfred Hopkinson (Aarhus University, Denmark) to TA2.12 Atomki-Queen’s University Ice Laboratory for Astrochemistry (Hungary).
Dates of visit: 04-08 December 2023

Report Summary: During this TNA visit, the simplest amino acid glycine (NH2CH2COOH), and its deuterated analogs, partially deuterated d3-glycine (ND2CH2COOD) and fully deuterated d5-glycine (ND2CD2COOD), were irradiated using 10 KeV protons. The subsequent products of this processing were then measured using infrared spectroscopy and a quadrupole mass spectrometer. The aim of this was to investigate the products of glycine destruction and investigate if this energetic processing could result in the formation of glycine peptides. The outcome of the TNA visit was the collection of infrared spectra of the irradiation of these molecules and then following this, temperature-programmed desorption measurements. These preliminary results show the formation of CO2, CO, and D2O.
