The kinetics of the gas-phase reactions of selected monoterpenes and cyclo-alkenes with ozone and the NO3 radical

► Measurements of rate constants for the reactions of O3 and NO3 with terpenes and cyclo-alkenes are presented. ► The effect of structure on the observed kinetics is discussed. ► Measured values are evaluated along with literature data to give recommended rate constants. ► Atmospheric lifetimes and presented in light of this data.
