COHERENT CONTROL OF ELECTRONS IN MOLECULES

Coherent superposition of electronic states can be achieved by simulta neous laser excitation at different frequencies. As an example, the th ree-level system is examined in order to demonstrate the possibility o f phase control of electron transfer in molecules. Ab initio calculati ons are used to illustrate the principle in a charge transfer molecule DMBAN, 4-(N,N-dimethylamino)benzonitrile.
