Additional NMR Experimental Information
Details	Proton Driven Spin-Diffusion experiments were carried out using a triple 2.5-mm Chemagnetics/Varian T3 probe at a static magnetic field of 14.09 T. Three 2D 13C-13C correlation spectra have been recorded with 100, 250 and 400 ms mixing time at 12 kHz magic angle spinning (MAS) and a sample temperature of 269 K.
