Dr. Zhang's research concentrates on fundamental aspects of atmospheric chemistry. He applies laser spectroscopy, mass spectrometry, and molecular beam techniques to investigate elementary photochemical processes and reaction mechanisms of atmospheric fr ee radicals and small molecules. Specifically, his research focuses on characterizing the key intermediates in tropospheric oxidation processes, i.e., alkyl, alkyl peroxy, and alkoxy radicals. Photochemistry and reactions of these intermediates will be studied by using the various approaches. These studies will address questions concerning free radical spectroscopy, thermodynamics, photochemistry, reaction products, and reaction mechanisms, and they could provide a basis for detailed understanding of m ore complex problems.
