High temperature rate constants for H/DÂ +Â n-C4H10 and i-C4H10

To our knowledge, the present experiments are the first direct measurements for the title reactions and the rate constants from this combined experimental/theoretical effort are recommended for use in combustion modeling. Results from the present studies on n-C4H10 and i-C4H10 along with prior studies on C2H6 and C3H8 suggest the applicability of rate rules for H + Alkanes that are based on generic primary, secondary, and tertiary abstraction sites.
