摘要：

The kinetic energy relased on the loss of a CH3 ⋅ radical from para substituted anisoles appears to depend on the nature of the substituent. The application of the dual parameter equation of Yukawa and Tsuno yields a linear correlation with the T0.5‐values. The mesomeric effect predominates strongly over the inductive effect.
