Dr. de Lijser's research interests are in the area of environmental organic photochemistry. Currently we are studying the structure and reactivity of naturally occurring compounds (drugs, pesticides, dyes) containing a carbon-nitrogen double bond (oximes, oxime ethers, hydrazones, azines) upon photochemical excitation and one-electron oxidation. Specific interests include the generation of reactive species (radicals, radical ions) via surface-catalyzed photochemical reactions (pesticides; environmental) and enzyme-catalyzed oxidations (drugs; toxicology) of model compounds.
