Investigation of the Electronic Structure of Alkyl Allyl Radicals

Abstract

The electronic structure of the homologous series of CH₃(CH₂)_nCHCHCH₂ (n = 0÷5) allyl all radicals is studied. The obtained spin density distribution is used to determine the fragment serving as the radical center. The delocalization of spin density over the basin of the radical center is shown to be responsible for two free valencies associated with two classical canonical structures (the conjugated fragment). The conjugation phenomenon is studied and electronic parameters are determined for the “standard” conjugated fragment CHCHCH₂.
