Comments:
H· + n-C3H7CHO are formed from chemically activated decomposition of the initial n-C4H9O adduct.
Reaction consists of H abstraction and an association reaction to form "hot" n-C4H9O. The latter reaction may exhibit a pressure dependent rate so the branching ratio may be pressure dependent. Present results are near the low pressure limit.
Branching ratio is based on the three observed reaction channels. Four other possible channels were identified but no products stemming from these channels were observed. Ab initio calculations by authors suggest each of these four channels could contribute (0.5 to 2)% of the total reactivity.
