When the protomproton decoupled heteronuclear two-dimensional chemical shift correlation experiment is applied to a molecule containing methylene groups, the spectra show not only the expected signals at the two proton chemical shifts, but also a strong artifact. This artifact appears at the average
The magnitudes and orientations of the 15 N chemical shift tensor of [1-15 N]-2-deoxyguanosine were determined from a polycrystalline sample using the two-dimensional PISEMA experiment. The magnitudes of the principal values of the 15 N chemical shift tensor of the N1 nitrogen of [1-15 N]-2-deoxygua
Recent application of two-dimensional (2D) 13C{'3C} double-quantum correlated ['3C{'3C}DQC] nmr spectroscopy to the study of uniformly labeled proteins has enabled extensive assignments of 13C resonances. '-3 In analyzing the 13C spin systems of tryptophan residues in flavodoxin and cytochrome k3 fr
