Vladimir L. Orkin (Fed)

Research Chemist

Vladimir L. Orkin's research interests include gas-phase chemical kinetics, atmospheric chemistry, and photochemistry.

His efforts focused on improving the accuracy and reliability of laboratory measurements of rate constants of gas-phase reactions involving the hydroxyl radical (OH), which determine the residence time of natural and industrial pollutants in the atmosphere. 

Along with measurements of the absorption spectra of atmospheric pollutants in the ultraviolet (UV) and infrared (IR) spectral regions, this creates a database for assessing the environmental impact of chemical compounds – their impact on the Earth's stratospheric ozone layer, atmospheric warming, and local tropospheric pollution.

Vladimir Orkin is a member of the NASA Panel for Data Evaluation, has contributed to the maintenance of the NIST Chemical Kinetics database and the WMO Scientific Assessments of Ozone Depletion.
