The structural dependence of geminal and vicinal CC coupling constants

Jung‐Hyuck Cho, Martin Klessinger, Ute Tecklenborg, Konrad Wilhelm

Open publisher page 20 citations

Abstract

Abstract CC coupling constants of ten bicyclic hydrocarbons and ten cyclic ethers or carbonyl compounds were determined from the satellites of broad band decoupled spectra or from INADEQUATE measurements. The influences of valence angles, dihedral angles, hybridization and heterosubstitution on geminal and vicinal CC coupling constants are discussed in terms of the algebraic additivity of the contributions from individual coupling paths within the framework of a multiple path mechanism.
