摘要
The kinetics of conformation‐dependent charge delocalization in radical cations generated from a series of α,ω‐diaminoalkanes, (CH3)2N(CH2)nN(CH3)2, (n = 1–3) in a 3‐methylpentane glassy solution at 90 K are discussed in terms of dispersive kinetics with the use of the time‐dependent rate constant in the form k(t) = Btα − 1. It was found that the activation energy distribution function became broader as the number of methylene groups separating the two nitrogen atoms increased, and that this process was accompanied by a substantial increase in the mean value of the activation energy.
