Alkyl nitrate yields from the NO x photooxidations of neopentane, 2-methylbutane and 3-methylpentane have been determined over the temperature and pressure ranges 281–323 K and 54–740 torr, respectively. The formation of the alkyl nitrates is attributed to the reaction pathway
and rate constant ratios k 1b/(k 1a+k 1b) are estimated, where (1a) is the reaction pathway
A method for estimating this rate constant ratio for primary, secondary and tertiary alkyl peroxy radicals is presented.
