✦ Synopsis

The solid state "C NMR spectral lineshape of a carbon atom directly bonded to a quadrupolar nucleus can take the form of an asymmetric multiplet in magic-angle spinning experiments. In this study, we have obtained spectra at various B0 field strengths of a sugar molecule deuterated at a specific position. The spectrum of this molecule, acquired using the dipolardephasing pulse sequence, was much simplified, containing essentially only signals assigned to the deuterated carbon. Lineshape simulations were found to be the most successful for spectra acquired at higher magnetic field strengths.
