Prof. Arnold research group has extensive expertise in the application of ultra-fast laser techniques to explore photochemical reaction mechanisms. His group has developed applications of time-resolved linear dichroism spectroscopy to gain an understanding of the orientational aspects of electron and energy transfer reactions. These studies have focused on the orientation of photoproducts relative to the initial orientation of the starting materials to obtain important mechanistic information. Parallel efforts have established new models for the prediction of transition moment vectors in charge-transfer complexes and in the rotational dynamics of excited probes in solution.
More recently Prof. Arnold has established a research program aimed at developing coherent back-scattered laser spectroscopy as a potential method to detect analytes in the vapor phase. Temporal and spatial focusing of high power ultra-short laser pulses are used to measure stimulated Raman scattering, laser induced plasma emissions, multi-photon absorption, and laser induced fluorescence.
