The objective of our research is the production of cyclic-ozone. Our hope is that the proper photonic reagent (pulse shape) will provide the necessary time dependent electric field to generate cyclic-ozone from its bent isomer. A pulse shaper, coupled with a genetic algorithm, will be used to seek out the proper pulse shape to perform the isomerization reaction. Detection will be performed using femtosecond CARS (Coherent Anti-Stokes Raman Spectroscopy), arranged in a folded-BOXCARS configuration. Significant progress has been made towards our goal of cyclic-ozone production. First, we have performed a detailed analysis of the electronic structure of the cyclic isomer. This analysis is essential for developing a proper detection scheme upon formation of the desired product. |

On the experimental side, we have investigated the signal (both resonant and nonresonant) generated from femtosecond CARS. This analysis has led us to develop a theoretical description which provides a means of obtaining the Raman line shape within a large nonresonant background as well as a complete description of the phase matching conditions for the folded-BOXCARS beam configuration. |

We have optimized the production of bent ozone from oxygen using the aforementioned pulse shaping technology. In addition to being an experimentally less complex analogue to the production of cyclic-ozone, this experiment demonstrates the use of coherent control of a chemical reaction where a neutral (as opposed to ionic) product is detected as well as the viability of the experimental approach we have undertaken.
