State-to-state dynamics of the H+CD3(CH2)4CD3→H2+CD3((CH2)3CH)CD3 reaction: Dynamics of abstraction of secondary H in linear alkanes

Quantum state distributions for the H2 product of the reaction of H atoms with CD3(CH2)4CD3 at 1.6 eV collision energy have been measured to characterize the dynamics of hydrogen atom abstraction at secondary sites in linear alkanes. The measured distributions are compared with those obtained previously for the H+n-C6H14→H2+C6H13 reaction. The two distributions are quite similar. The small differences seen between them are evaluated within a local reaction model developed for these types of reactions.
