The stable carbon isotope fractionation for reactions of selected hydrocarbons with OH-radicals and its relevance for atmosphere chemistry
Measurements of the kinetic isotope effect (KIE) for the reactions of light n‐alkanes as well as for several unsaturated hydrocarbons, including alkenes, dienes, benzene, and ethyne with OH‐radicals are presented. All ...
Emissions of methyl chloroform (CH3CCl3) from biomass burning and the tropospheric methyl chloroform budget
The only known sources of atmospheric methyl chloroform are industrial production and biomass burning. With the phase‐out of industrial methyl chloroform production the atmospheric burden of methyl chloroform is rapidly ...
The Stable Carbon Isotope Ratio of Biogenic Emissions of Isoprene and the Potential Use of Stable Isotope Ratio Measurements to Study Photochemical Processing of Isoprene in the Atmosphere
(Springer Netherlands, 2003)
A technique was developed that allows the determination of the stable carbon isotope ratio of isoprene in air. The method was used for a limited number of ambient measurements as well as laboratory studies of isoprene ...
Determination of external and internal mixing of organic and inorganic aerosol components from hygroscopic properties of sub micrometer particles during a field study in the lower Fraser Valley
(Taylor & Francis, 2004)
A tandem differential mobility analyzer (TDMA) system was developed to measure particle growth factors over a range of relative humidities from 50-85%. This system was deployed in the Lower Fraser Valley, and data was ...
Atmospheric measurements of HONO by tunable diode laser absorption spectroscopy
(Springer Verlag, 2001)
Ambient gas phase nitrous acid (HONO) has been measured by Tunable Diode Laser Absorption Spectroscopy with sub-ppbv detection limits. An R-branch line in the 1263.4 cm–1 3 band was found tobe free of interference and ...
Concentration and stable carbon isotopic composition of ethane and benzene using a global 3D isotope inclusive chemical tracer model
A three-dimensional global chemical tracer model of the atmosphere has been adapted to include the stable carbon isotopic composition and isotopic fractionation of ethane and benzene. For computational efficiency the ...
