A pulse sequence that yields three-dimensional (1)H chemical shift/(1)H-(15)N heteronuclear dipolar coupling/(15)N chemical shift solid-state NMR spectra is demonstrated on a uniformly (15)N labeled membrane protein in magnetically aligned phospholipid bilayers. Based on SAMPI4, the pulse sequence yields high resolution in all three dimensions at a (1)H resonance frequency of 900 MHz with the relatively low rf field strength (33 kHz) available for a lossy aqueous sample with a commercial spectrometer and probe. The (1)H chemical shift frequency dimension is shown to select among amide resonances, which will be useful in studies of larger polytopic membrane proteins where the resonances overlap in two-dimensional spectra. Moreover, the (1)H chemical shift, which can be measured from these spectra, provides an additional orientationally dependent frequency as input for structure calculations.
