Radical-induced PRE of DMPC membranes. Left column: 1H MAS spectra. Right column: 13C MAS spectra measured with DP (a–c) and CP (d–e). All spectra were measured at 298 K on a 400 MHz spectrometer. (a–c) Glycerol-protected DMPC membranes without radical (a), with 10 mM AMUPol (b), and with 10 mM TOTAPOL (c). (d–e) Hydrated DMPC membranes without cryoprotectants. (d) Without radical. (e) With 10 mM AMUPol. The S/S0 values in (b, c) are calculated with respect to the control spectra in (a), while the S/S0 values in (e) are calculated with respect to (d). The 13C S/S0 values are further normalized with respect to the chain-end ω peak at 14.2 ppm.
