合成無機ポリマー中におけるＮ，Ｎ，Ｎ′，Ｎ′‐テトラメチル‐ｐ‐フェニレンジアミンカチオンラジカルの分子運動とＥＳＲスペクトル

Abstract

The line width of each hfs line in ESR spectrum of a cation of N, N, N′, N′-Tetramethylpphenylenediamine (TMPD.+) formed in a mixture with butyl titanate polymer varies with the nuclear spin quantum number. Simulation of the ESR spectrum of TMPD.+ has been made using the line width which varies with nuclear spin quantum number. The contribution of τc(A-B) m1/h2 term to the line width was investigated to see which of the mIvalues, mI of benzene ring protons, mI, of methyl protons, or m, of nitrogen nuclei, is contributing most.The result indicates that the line width originating from the protons of the benzene ring is nearly 10 times as large as those coming from the protons of the methyl groups and the nitrogen nuclei. Therefore TMPID.+ in the butyl titanate polymer is considered to be fixed at the phenyl ring.
