Measuring the catalytic impact of nonresonant, pulsed radiation on reactions in the gas and solution phases
Abstract/Contents
- Abstract
- Light exists as a propagating wave of electric and magnetic fields. Exploration of the interactions between resonant light and matter has provided us with a wealth of structural and dynamical information. Largely overlooked, however, is the impact of nonresonant radiation which, when introduced into a reaction system from an intense, pulsed laser beam, may induce changes in the system through its associated strong electric field. At field strengths of 10 MV/cm, off-resonant radiation can influence the course of a reaction by interacting with the molecular system's polarizability, α, to lower an activation barrier directly. Because there is no net consumption of nonresonant photons, they behave as catalysts rather than reactants in a process referred to as "laser-field catalysis, " or "photon catalysis." In the experimental work presented in this dissertation, I investigate the impact(s) of a nonresonant IR field (1064 nm) on photoreactions in both the gas and solution phases: the photodissociation of deuterium iodide (gas), the photodissociation of phenol (gas), and the photoisomerization of cis-stilbene to trans-stilbene (solution). Two possible roles of the electric field, alignment of reagent molecules and dynamic Stark shifting of potential energy surfaces, are considered. Theoretical calculations are used to support experimental interpretation of results
