Simulated dependence of the 13C-13C polarization transfer efficiency on the isotropic chemical shift difference for various R2nv symmetry sequences: (a) R211, (b) R212 (DARR), (c) R221, and (d) R221. The simulations were performed in SIMPSON and the model spin systems contained 2 protons and 2 carbons. The MAS frequency was 40 kHz, and the mixing time was 4 ms. Note, that the simulated resonance frequency offsets are ±25 kHz covering the entire spectral range for 13C at the magnetic field of 14.1 T.
