Chemistry Department Colloquium

"Direct Imaging Studies of Atmospheric Photochemistry: From Energetics to Roaming Dynamics"

Presented by Dr. Simon North, Chemistry Department, Texas A&M University

Wednesday, March 9, 2011, 11:00 am — Hamilton Seminar Room, Bldg. 555

A detailed understanding of the photochemistry of radical intermediates is critical for accurate modeling of the atmosphere. Our work seeks to establish quantitative trends in the wavelength dependent photochemistry to aid in assessing atmospheric significance. Our group utilizes molecular beam velocity-map ion imaging to study the photodissociation of isolated, jet-cooled, radicals of relevance to atmospheric chemistry. The technique permits direct determination of final products, the distribution of excess energy, and accurate energetic. Careful analysis of the data can also reveal the underlying molecular choreography during the reaction. This presentation will highlight recent results on several target species including halogen oxides and the nitrate radical (NO3) that have been investigated at Texas A&M University.
