To eliminate the influences of field inhomogeneity on the conventional 2D correlation spectroscopy (COSY), two schemes via spatially encoded intermolecular multiple-quantum coherences combined with Hadamard encoding and three-dimensional acquisition respectively were proposed to achieve high-resolution 2D COSY in inhomogeneous fields with high acquisition efficiency. Compared to the conventional method, the acquisition time is shortened by orders of magnitude. The new schemes may be useful for the study of chemical and biological materials.
