Fentoquímica: acompanhando reações químicas em tempo real

In the last twenty years Chemical Dynamics has emerged as a strong area in Chemistry. Its foundations deals with the mechanisms and time scales involved in the breaking and making of a chemical bond. We present here theoretical studies of the dynamics of molecular processes illustrated with examples of H transfer reactions, unimoleculat decomposition and molecular excitation.
More recently theorists and experimentalists are turning their interest toward controlling molecular processes rather than just explaining them. The fast progress in the development of high power ultrashort pulse lasers offers many interesting applications of real time observation of chemical reactions and control of its yields. This oppened a new branch of Chemical Dynamics called Femtochemistry caracterized by femtosecond time scale. We also present simulations of laser control of molecular photodissociation and review recent experimental applications. Some new perspectives and possibilities of industrial applications are also disscused.
