The rate constants obtained (in cm(3) molecule(-1) s(-1) units) were: for 4-methylenehex-5-enal, (1.55+/-0.15)x10(-10), (4.75+/-0.35)x10(-13) and (1.46+/-0.12)x10(-17) for the OH radical, NO3 radical and O-3 reactions, respectively; for (3Z)-4-methylhexa-3,5-dienal: (1.61+/-0.35)x10(-10), (2.17+/-0.30)x10(-12), and (4.13+/-0.81)x10(-17) for the OH radical, NO3 radical and O-3 reactions, respectively; for (3E)-4-methylhexa-3,5-dienal: (2.52+/-0.65)x10(-10), (1.75+/-0.27)x10(-12), and (5.36+/-0.28)x10(-17) for the OH radical, NO3 radical and O-3 reactions, respectively; and for 4-methylcyclohex-3-en-1-one: (1.10+/-0.19)x10(-10), (1.81+/-0.35)x10(-12), and (6.98+/-0.40)x10(-17) for the OH radical, NO3 radical and O-3 reactions, respectively. These carbonyl compounds are all reactive in the troposphere, with daytime reaction with the OH radical and nighttime reaction with the NO3 radical being predicted to dominate as loss processes and with estimated lifetimes of about an hour or less.
