Proton-enhanced nuclear induction spectroscopy 13C chemical shielding anisotropy in some organic solids

Using the recently introduced technique of proton-enchanced nuclear induction spectroscopy, ¹³C chemical shielding parameters are reported for a number of simple organic compounds, and some exemplary spectra are shown. The ¹³C chemical shielding parameters are sensitive to the functional character of the carbon and to molecular structure. Several interesting aspects of these experiments, including molecular motion and cross-relaxation effects, are mentioned briefly.
