Dipolar local field measurements from indirect observation of 1H nuclei via cross-polarization 13C nuclear magnetic resonance spectroscopy.
An extension of the exploitation of a simple pulse sequence designed for indirect observation of 1H nuclei through 13C resonances is presented. It is shown that by using this pulse sequence under conditions of rapid magic-angle rotation and coherent energy transfer between directly bonded protons and carbons, an insight into the local dipolar interactions is available in typical organic solids.
