Summary on Grant Application Form |
|
We propose to develop and use a novel technique that detects the radiation that is produced when a molecule undergoes an ultrafast charge-transfer reaction. By measuring this radiation (at THz frequencies) with electro-optic sampling techniques, it is possible to extract a direct and unambiguous measure of the instantaneous amount of charge transferred, avoiding the interpretational problems of conventional spectroscopy. Theoretical models will be developed that describe the generation, near-field propagation, and detection of electromagnetic radiation by microscopic currents. These theoretical models will be tested on representative systems undergoing various form of charge transfer. The insights gained this way will be applied to find superior generators of terahertz radiation. The technique will be used to study challenging problems in charge transfer, such as the role of vibrational and electronic coherence in charge-transfer. It will for the first time be able to answer the question whether coherent excitations are in fact involved in the reaction or merely observers. The results of these experiments will be used to compare with and challenge modern charge-transfer theories.
