Two-dimensional SLF and HETCOR planes from three-dimensional spectra of a uniformly 13C, 15N labeled sample of polycrystalline methionine-leucine-phenylalanine obtained using the pulse sequence diagrammed in Figure 1A (SADO) at 700 MHz. A. 15N/13C two-dimensional heteronuclear correlation spectrum with 13C chemical shift and 15N chemical shift frequency axes. B. 13C/13C two-dimensional homonuclear correlation spectrum with 13C chemical shift frequency axes. C. 1H-15N/13C two-dimensional separated local field spectrum with 13C chemical shift and 1H-15N heteronuclear dipolar coupling frequency axes. (It corresponds to the 15N chemical shift frequency at 128 ppm marked with an arrow in Panel A.) D. 1H-13C/13C two-dimensional separated local field spectrum with 13C chemical shift and 1H-13C heteronuclear dipolar coupling frequency axes. (It corresponds to the methionine 13C chemical shift frequency at 52 ppm marked with an arrow in Panel B.)
