Abstract

For H‐atom abstraction reactions by HO radicals it has been shown that
equation image
If D~i~ is taken as the CH bond dissociation enthalpy at 298 K, then a = 0.323 and D~0~is obtained from the empirical formula
where D~0~ is in kcal/mol and T is in K. Thisrelationship is valid for T between 200 and 400 K. Finally empiricalrelationships are given to help estimate D~i~.
