Low-temperature MAS NMR measurements of ortho-CH sites in u-[2H,15N],Phe-ortho-13C1H-labeled TET2. (A) CP-based 1H-13C correlation spectra at temperatures down to 100 K (as indicated) and a MAS frequency of 40 kHz. (B,C) Temperature-dependent 13C R1ρ and R1 relaxation rate constants from one-di-mensional 1H-detected measurements, using the pulse sequence shown in Figure S2D,E.
