abstract = {Degradation of isoprene, m-xylene, n-octane, propene, and
methacrolein by hydroxyl radicals has been studied in the
simulation chamber SAPHIR under burden of trace gases as
they are typical for the moderately polluted planetary
boundary layer. Measured time series of the hydrocarbon
mixing ratios and the OH concentrations were used to
determine the rate constants. The hydrocarbons were measured
with gas chromatography and proton transfer reaction mass
spectrometry. OH was measured with the Julich DOAS
(differential optical absorption spectroscopy) instrument.
In all cases except methacrolein good agreement was found
with the reference rate constants taken from theMaster
Chemical Mechanism ( MCM3.1). The data for methacrolein are
consistent with the results of Karl et al. ( J. Atmos. Chem
55, 2006, doi:10.1007/s10874-006-9034-x) who reported a
$12\%$ smaller value. The degradation of hydrocarbons
provides an independent method to analyse precision and
accuracy of the OH measurements. A precision of better than
$4\%$ over a period of nearly 4 months was found. The
accuracy is within the limitations given by the light
absorption cross section of OH. Both results are consistent
with earlier results by Hausmann et al.},
