Short summary

Here we report on a detailed study of the photochemistry and fate of a nitrooxy enal that is produced from the reaction of NO₃ with isoprene. We synthesized the 4,1-nitrooxy enal, purified it, and measured the O₃ and OH reaction rate constants, and determined the atmospheric photodissociation rate constant for specified radiation conditions. The determined fast photolysis rate and high reactivity toward OH lead to a lifetime of less than 1 hour, with photolysis being a dominant daytime sink.
