Multi-spin 13C-2H REDOR for measuring long distances 21. (a) Pulse sequence of the 13C-2H REDOR experiment. (b) 13C-2H REDOR dephasing of 13Cα, 2Hβ-labeled alanine. The REDOR minimum is 30% higher than the theoretical minimum due to incomplete inversion of the 2H polarization. (c, d) 13C-2H REDOR dephasing of Ser31 Cα by perdeuterated amantadine in membrane-bound M2TM. The measured dephasing was simulated in terms of the pore radius R and height Z of the carbon from the center of the drug. The geometry is displayed in (d).
