Mechanisms for Laser Control of Chemical Reactions

During the past several years our group has developed and employed a new technique for realistic simulations of the interaction of light with matter. Recent simulations of laser pulses interacting with molecules clearly demonstrate the potential for control of chemical reactions, through various mechanisms which include the following: (i) excitation of electrons to states which have different b...

Ultrafast Laser Spectroscopy of Chemical Reactions

Ultrafast laser spectroscopy has extended reaction-dynamic studies into the dcosecond and femtosecond time domain. allowing for experimintal observations of transitory fragments that occur during collision or half-collision. This ability to observe molecular reactions allows real-time viewing of energy redistributions, measurements of state-to-state rates, and tests of microscopic statistical t...

Chemical salt reactions as algebraic hyperstructures

A salt metathesis reaction is a chemical process involving the exchange of bonds between two reacting chemical species, which results in the creation of products with similar or identical bonding affiliations. Hyperstructure theory is studied from the theoretical point of view and for its applications. In this paper, we provide some examples of hyperstructures associated with salt m...

Modeling and Simulating Chemical Reactions

Many students are familiar with the idea of modeling chemical reactions in terms of ordinary differential equations. However, these deterministic reaction rate equations are really a certain large-scale limit of a sequence of finer-scale probabilistic models. In studying this hierarchy of models, students can be exposed to a range of modern ideas in applied and computational mathematics. This a...
