P. Palmas et al., DIPOLAR LOCAL-FIELD MEASUREMENTS FROM INDIRECT OBSERVATION OF H-1 NUCLEI VIA CROSS-POLARIZATION C-13 NUCLEAR-MAGNETIC-RESONANCE SPECTROSCOPY, Solid state nuclear magnetic resonance, 4(2), 1995, pp. 105-111
An extension of the exploitation of a simple pulse sequence designed f
or indirect observation of H-1 nuclei through C-13 resonances is prese
nted. It is shown that by using this pulse sequence under conditions o
f rapid magic-angle rotation and coherent energy transfer between dire
ctly bonded protons and carbons, an insight into the local dipolar int
eractions is available in typical organic solids.
