The splitting pattern of the P-H5" (and P-H5') cross-peak in a 2D 31P-1H correlated NMR spectrum is analysed. Since this cross-peak pattern is strongly dependent on two coupling constants, 'J(PH5") and 3J(H4H5"), it is an efficient probe for the backbone torsion angles fl and y in nucleic acids. A m

## Abstract It is demonstrated that in a case where neither the proton nor the natural‐abundance ^13^C‐satellite spectra of a partially oriented molecule carry enough structural information, one can determine the entire molecular geometry by the combined use of several liquid crystals as solvents.
