| Abstract
| - In this contribution, we consider the interaction of glycine, a small, model biomolecule, and its zwitterionwith fast ion radiation. The object of the study is to determine the differences in properties among variousconformers and orientations of the neutral molecule and the zwitterion and to determine if these differenceswill have implications in terms of radiation protection and radiation therapy. To this end, quantum mechanicalcalculations were carried out on three conformers of the neutral molecule and two of the zwitterion to determineboth the isotropic and directional components of the moments of the dipole oscillator strength distribution ineach case. It is these moments that determine the interaction of swift radiation with a molecule.
