A. and B. 15N/13C HETCOR spectra obtained with 1H-irradiation of 60 kHz with 1ms and 3ms 15N/13C mixing times, respectively, of a 15N, 13Cα NAL single crystal. One-dimensional spectra on the top and the side are the 13C and 15N CP spectra shown in Figure 2 A and B. Strong inter-molecular correlations in a single crystal are achieved only under the higher mismatched condition.
