Chemistry & Biochemistry Seminar Series: Paul O. Wennberg '85

Thursday, February 20 at 4:45am

Science Center, A255
119 Woodland Street, Oberlin, OH 44074

The Department of Chemistry and Biochemistry hosts guest speaker Paul O. Wennberg '85, R. Stanton Avery Professor of Atmospheric Chemistry and Environmental Science and Engineering at the California Institute of Technology. His presentation is in honor of the retirement of Robert Q. Thompson and will be on the topic of ‘‘Formation of organic hydroperoxides in the atmosphere via autoxidation.’’

The seminar will be preceded by a light reception at 4:30 p.m. in the David Love Lounge.

Sponsored by the Luke E. Steiner Lecture Fund.

Abstract:

As a result of controls on nitric oxide (NO) emissions from cars, trucks, and electricity production, NOx levels (sum on NO and NO2) have decreased rapidly across North America over the past decades. The reductions in NO alter the photochemical pathways in the oxidation of numerous chemicals emitted from the biosphere and from anthropogenic activities. The gas phase chemistry in the low NO regime has received significantly less attention from atmospheric chemists.

Here, I describe new analytical methods to probe this regime in the field and in the laboratory. New chemical pathways, including autoxidation leading to the formation of organic hydroperoxides are identified.
