A kinetic model was compiled to simulate reactions of the monoterpenes, α-pinene and Δ3-carene, with O3, NO2 and NO. The influence of different initial settings of O3, NO2 and NO on the monoterpene reaction was evaluated. At initial levels of 75 p.p.b. of O3, NO2 and NO each, 1.5% of α-pinene and 1.1% of Δ3-carene were calculated to react after 215 s. The corresponding experimental results showed that 9.3–12.2% of α-pinene and 9.9–11.7% of Δ3-carene reacted. The calculated levels of O3, NO2 and NO were compared to experimental measurements and were shown to correspond well. However, comparison of the amount of monoterpene reacted between calculated and experimental results, demonstrated that the calculations underestimated the amount of monoterpene reacted in the experimental chamber. The difference between experimental and calculated results could, e.g., be the effect of surfaces and the presence of water, which are parameters not included in the kinetic model known to have influence on these reactions.
