      abstract     = {The oxidation of Δ3-carene and one of its main oxidation
                      products, caronaldehyde, by the OH radical and O3 was
                      investigated in the atmospheric simulation chamber SAPHIR
                      under atmospheric conditions for NOx mixing ratios below
                      2 ppbv. Within this study, the rate constants of the
                      reaction of Δ3-carene with OH and O3 and of the reaction of
                      caronaldehyde with OH were determined to be
                      (8.0±0.5)×10−11 cm3 s−1 at 304 K,
                      (4.4±0.2)×10−17 cm3 s−1 at 300 K and
                      (4.6±1.6)×10−11 cm3 s−1 at 300 K, in agreement
                      with previously published values. The yields of
                      caronaldehyde from the reaction of OH and ozone with
                      Δ3-carene were determined to be 0.30±0.05 and 0.06±0.02,
                      respectively. Both values are in reasonably good agreement
                      with reported literature values. An organic nitrate (RONO2)
                      yield from the reaction of NO with RO2 derived from
                      Δ3-carene of 0.25±0.04 was determined from the analysis of
                      the reactive nitrogen species (NOy) in the SAPHIR chamber.
                      The RONO2 yield of the reaction of NO with RO2 derived from
                      the reaction of caronaldehyde with OH was found to be
                      0.10±0.02. The organic nitrate yields of Δ3-carene and
                      caronaldehyde oxidation with OH are reported here for the
                      first time in the gas phase. An OH yield of 0.65±0.10 was
                      determined from the ozonolysis of Δ3-carene. Calculations
                      of production and destruction rates of the sum of hydroxyl
                      and peroxy radicals (ROx=OH+HO2+RO2) demonstrated that there
                      were no unaccounted production or loss processes of radicals
                      in the oxidation of Δ3-carene for conditions of the chamber
                      experiments. In an OH-free experiment with added OH
                      scavenger, the photolysis frequency of caronaldehyde was
                      obtained from its photolytical decay. The experimental
                      photolysis frequency was a factor of 7 higher than the value
                      calculated from the measured solar actinic flux density, an
                      absorption cross section from the literature and an assumed
                      effective quantum yield of unity for photodissociation.},
