Title: Chemical activation in unimolecular reactions of some unsubstituted alkoxy radicals
Journal: Phys. Chem. Chem. Phys.
Volume: 5
Page(s): 4653 - 4655
Year: 2003
Reference type: Journal article
Squib: 2003CAR/FOR4653-4655
Reaction:
2-C4H9O → CH3CHO + ·C2H5
Reaction order:
1
Rate expression:
no rate data available
Category: Theory
Data type:
Transition state theory
Comments:
The article demostrates that in a ROO + NO -> RO + NO2 reaction (where R = sec-C4H9) a significant fraction of the 2-butoxy radical is formed in a chemically activated state, which decomposes on a sub-nansecond scale. This fraction of butoxy radicals are thus removed from a competition with bimolecular reactions (e.g., with O2), with cosequences for the overall kinetics of observable experimental systems.
