Experimental CPVC spectra (red) of the Cα sites in MLF (the spectra of the three residues added together) measured in the 1.6 mm probe at 40 kHz with a 1H RF of 100 kHz and 13C RF of 54, 60, and 66 kHz, plotted together with corresponding simulated spectra (black) with DCC = 22.5 kHz,
and the three
differences of (a) 52 kHz, (b) 44 kHz, and (c) 38 kHz.
