Multiple-Quantum and Two-Dimensional NMR,uid crystals was mentioned at the end of Chapter 3. The carbon-proton dipolar couplings were determined by combining near magic-angle spinning of the sample and the separated local field spectroscopy . A 2D .F spin echo experiment on a sample rotating near the magic-angle has also been reported
