Intermolecular multiple quantum coherences (iMQCs) caused by long-range dipolar interactions possess some appealing unique properties for high-resoultion NMR spectroscopy in inhomogeneous fields. In this abstract, a new iMQC method involving Hadamard encoding is proposed to obtain high- resolution 1D NMR spectrum in inhomogeneous fields within a short acquisition time. Its application on simple and complex systems was tested. Experimental results indicate that the spectral line-width can be considerably reduced and the signal to noise ratio can be improved.
