Evaluation of the rate coefficients and arrhenius parameters of hydrogen atom transfer reactions. II. Application of the method

The bond‐strength–bond‐length (BSBL) method was used to estimate Arrhenius parameters and rate coefficients for various hydrogen atom transfer reactions of the type A + BC → AB + C. In most cases predicted activation energies agreed within 1.2 kcal/mol with the experimental values (average error = 1.12 and standard deviation = 1.42), and the calculated log A agreed within 0.55 log units with the literature data (average error = 0.47 and standard deviation = 0.57). Predicted activated complex properties were shown to agree very well with potential energy surface properties obtained from ab initio quantum mechanical calculations. Detailed comparison of the BSBL results and the results of bond‐energy–bond‐order (BEBO)‐type calculations are presented.
