Dynamics of light-induced bimolecular reactions

Research group no. 8

Dynamics of light-induced bimolecular reactions

Group leader

Dr. hab. Angulo Nunez Gonzalo Manuel

Research topics

Our major concern is to find physical background to chemical reactivity. To this end, we compare our mesurements of the kinetics of photo-excited products with the most advanced statistical theories. We are especially interested in reactions occuring in complex media mimicking living cells.
