abstract = {An assessment of the accuracy of OH concentrations measured
in a smog chamber by a calibrated laser-induced fluorescence
(LIF) instrument has been made, in the course of 9
experiments performed to study the photo-oxidation of
benzene, toluene, 1,3,5-trimethylbenzene, paraxylene,
ortho-cresol and ethene at the European Photoreactor
facility (EUPHORE). The LIF system was calibrated via the
water photolysis/ozone actinometry approach. OH
concentrations were inferred from the instantaneous rate of
removal of each hydrocarbon species (measured by FTIR or
HPLC) via the appropriate rate coefficient for their
reaction with OH, and compared with those obtained from the
LIF system. Good agreement between the two approaches was
found for all species with the exception of
1,3,5-trimethylbenzene, for which OH concentrations inferred
from hydrocarbon removal were a factor of 3 lower than those
measured by the LIF system. From the remaining 8
experiments, an overall value of 1.15+/-0.13 (+/-1sigma) was
obtained for [OH](LIF)/[OH](HydrocarbonDecay), compared with
the estimated uncertainty in the accuracy of the water
photolysis/ozone actinometry OH calibration technique of
$26\%$ (1sigma).},
