Understanding the aqueous phase ozonolysis of isoprene: distinct product distribution and mechanism from the gas phase reaction [PDF]

open access: yes, 2012
The aqueous phase reaction of volatile organic compounds (VOCs) has not been considered in most analyses of atmospheric chemical processes. However, some experimental evidence has shown that, compared to the corresponding gas phase reaction, the aqueous ...
