Special Issue on Solar Energy and Applied Photochemistry


Intramolecular dynamics of two linear molecules HCN and CO2 are studied by computing trajectories, plotting Poincaré sections and calculating Lyapunov exponents. The process of dissociation is then studied by the same technique for HCN in the presence of a strong CO2 laser. Results of these preliminary calculations unequivocally show a threshold intensity for dissociation which is possible to verify experimentally.
