A) The chemical structure of the YAF peptide. B) Aromatic region of the 2D 13C-13C RFDR spectrum of YAF. C) Dipolar lineshapes for cross peaks corresponding to the different aromatic carbons in Tyr and Phe residues of YAF, extracted from the 3D CPVC-RFDR spectrum. The experimental and best-fit simulated lineshapes are shown as black and blue lines, respectively.
