abstract
By exposing molecules to ionizing radiation, radical species are formed. What appears as surprising is that even immediately after exposure to the radiation (as measured by doing experiments at liquid helium temperatures), there is a high degree of specificity in the radial production. This selectivity has been examined in crystals of the carbohydrate α-L-rhamnose by use of density functional theory calculations and periodic boundary conditions. In this molecule only one oxidation product is observed in experiments1,2, though three additional very similar radical species might in principle be produced. It is found that the observed product corresponds to a molecular conformation of slightly lower energy and a more preferable formation reaction path than the other three possible products3. The next step in understanding the radiation physics if this system will be to investigate the mechanisms behind the reduction product formations. References 1 P. O. Samskog and A. Lund, Chem. Phys.
