摘要: Valence bond theory and observed hyperfine splitting data are used to calculate proton‐proton spin‐spin couplings that arise through long range correlation of π‐electron spins in even alternate aromatic hydrocarbons. In benzene naphthalene calculated spin coupling constants positive for protons separated by an odd number carbon‐carbon bonds negative bonds.
