NEWS! Research of former undergrad highlighted in Nature! Alyson Lanciki (B.S. 2006) is doing her Ph.D. research with Professor Cole-Dai at South Dakota State University. Her thesis research includes work published in Geophysical Research Letters and highlighted under "Volcano Chills" in the November 12 issue of Nature. Congratulations, Alyson! More News ...

Research Summary

The Dibble group investigates gas phase chemistry of organic radicals, focusing on atmospheric chemistry. We have long been involved in studying the reaction pathways of alkoxy radicals (RO) in the lower atmosphere, in the context of formation of photochemical smog and the global oxidizing capacity of the atmosphere. Another interest has been the atmospheric chemistry of isoprene. We have begun investigating the use of electron beams and plasmas to degrade airborne pollutants. A new project involves the unimolecular reactions of peroxy radicals that initiate combustion of biodiesel fuels.

Experimental studies employ lasers to probe for stable and transient species. Both reaction kinetics and the spectroscopy of new species have been studied using laser-induced fluorescence (LIF). Cavity ringdown spectroscopy in the near infrared is also used. We carry out ab initio and density functional calculations to map out thermochemical kinetics and to explore and interpret the spectroscopy of as-yet uncharacterized species. See the article about our computational work in Access, the magazine of the National Compuational Science Alliance.
