Dipolar dephasing curves for Q44-HttEx1 at variable temperature. (A) Simulated ¹³Cα-¹H dephasing curves based on R18₁⁷ -based ¹H–¹³C dipolar recoupling, for different order parameter values between 0.1 and 1 and with 0.5 ms relaxation (Lin et al., 2017). (B) Experimental dephasing curves of the ‘a’ and ‘b’ glutamine types at 277 K, and (C) at 256 K. (D) Experimental dephasing curves of prolines from PPII helices (red, blue) and from the random coil conformation (grey) at 277 K, and (E) at 256 K. Experimental data were measured at 600 MHz (¹H) and 8 kHz MAS. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
