Bally group

Our general interest is in the chemistry and spectroscopy of reactive intermediates, mostly of organic origin, which we investigate by electronic and vibrational spectroscopy by embedding them in cryogenic matrices (Freon glasses at 77K or argon matrices at 12K). By this technique we investigate carbenes, nitrenes, and radicals and occasionally also other transient species such as strained hydrocarbons, cumulenes etc. which we usually generate by some photochemical technique from suitable precursors. The focus of our current research is on the study of changes in chemical bonding or molecular structure on single-electron transfer as well as on the photochemistry of radical ions. In order to understand the mechanisms of such rearrangements, we employ different theoretical methods based on quantum chemistry to model our spectroscopic observation and the potential energy surfaces on which such rearrangements take place.
