Research interests

Chemical Physics is a perspective where chemical problems are approached as directly as possible. My interest with the direct observation of Physico Chemical problems has started with Non Radiative transitions where after the excitation of a non stationary state the ‘dark character’ appeared. This aspect was neglected in the time evolution of aromatic compounds.

I have thus been interested in Transitions State observation in chemical reactions by ultra fast lasers when this became possible and by time resolved electron spectroscopy as the signature of the electron distribution shuffling at this level [web]. This changes provide the necessary forces to drive the system over the TS to the products . Time resolved observation is complemented by spectroscopic methods which yield direct information on the local potential energy surface aspects at the Transition State level [web].
