AbstractNon‐uniform sampling in combination with homonuclear broadband decoupling along an indirect dimension, and indirect covariance processing are used to record ultrahigh resolution two‐dimensional TOCSY spectra in less than half an hour, for typical sample concentrations in the mm range. TOCSY correlations belonging to protons separated by as little as ≈2 Hz can be distinctly discerned. The utility of the technique for low concentrations has been demonstrated.
