Bichromophoric Molecules

Time resolved femtosecond probing of intramolecular energy flow after excitation of the two different infrared CH-chromophores in these bichromophoric molecules shows strong dependence on the chemical environment of the initial excitation.

Ligand Bond

Photoinduced spin transitions are studied by femtosecond electron diffraction to understand ultrafast structural dynamics associated with intersystem crossing. The results indicate the structural reorganization occurs within 2.3 ps, as the metal-ligand bond distribution narrows during intramolecular vibrational energy redistribution.
