The kinetic energy relased on the loss of a CH 3 ⋅ 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 T 0.5 ‐values. The mesomeric effect predominates strongly over the inductive effect.
