Figure 5.
13C CP NMR spectra of 1.9 mM melittin in partially deuterated water/glycerol/DMSO, with (red, 16 scans) and without (black, 32 scans, vertical scale divided by two) microwaves. Melittin was prepared with uniform 13C labeling of Pro14, Ala15, Leu16, and Ile17. See text for other details of sample conditions. Spectra were acquired at 25 K sample temperature with 6.5 kHz MAS and processed with 100 Hz Gaussian line broadening
