Vibrational averaging of residual dipolar couplings: dependence on orientational order

Abstract

Observed residual, inter-nuclear dipolar couplings are averages over vibrational motion. Calculations of this effect are made on the assumption that the vibrational modes can be approximated as harmonic in order to demonstrate the dependence on the orientational order of solute molecules dissolved in anisotropic solvents.
