Abstract

It will be demonstrated that the chemical shift anisotropy (CSA) relaxation mechanism for protonated aromatic 13C nuclei is by no means negligible. The cross correlation spectral density arising from dipolar and CSA interactions in the natural abundance 13C–H spin system of pentachlorobenzene is included in the complete determination of the molecular motional anisotropy. Additionally, the absolute sign of the indirect coupling constant 1JCH is shown to be positive.
