Coherent Control of Unimolecular Reaction Dynamics Based on a Local Optimization Schemeg fields. The coherent control theory is applied to three types of unimolecular reaction dynamics: dissociation of hydrogen fluoride, isomerization of hydrogen cyanide, and a pump — dump pulse control of a reaction via an upper electronic excited state. The results of these applications show that th

Ultrafast Relaxation and Nonlinear Localized Excitations in Conjugated PolymersA spectral shape changed within 1 ps. The middle PIA peak with about 100 fs decay constant is assigned as a hot self-trapped exciton (STE). The single-peak transition energy of the hot STEs (1.4 – 1.5 eV) was explained as a transition from the hot STE either to an electron-hole threshold or to a bie

Progress toward manipulation and control of reactions using lasers in various laboratories around the world is also described.978-3-642-64154-1978-3-642-59855-5

Structures and Dynamics of Excited Electronic States and Ionic Radicals Studied by Time-Resolved Ramsecond and nanosecond time-resolved Raman spectroscopy was employed with the aid of laser flash photolysis and . molecular orbital calculations. It was observed that the multiple bonds such as C≡C, C=C, C=O, C=N and phenyl rings were weakened in both the excited electronic states and ionic radicals;

Excited State Dynamics and Chemical Control of Large Moleculesg their outcome. We examine ways in which spectroscopic observations can be used to construct models for electronic excited states and infer the relevant nuclear dynamics on them. Our methods are applied to the well-studied photoisomerization reactions of stilbene and used to explore two photon (IR
