✦ Synopsis

A number of modified two-dimensional NMR pulse sequences FIDs in the indirectly detected (t 1 ) domain after the Fourier have been developed to suppress the diagonal peaks which may transformation of the directly detected (t 2 ) domain. These introduce severe spectral distortions, such as t 1 -ridges and large FIDs are reconstructed following the removal of the largest dispersive signals on the diagonal. However, these modifications singular values. The final spectrum which is free of the increase the minimum number of scans, require more complicated dispersive resonances can be obtained by Fourier transforexperimental designs, and often decrease the sensitivity of the mation of the t 1 domain. We demonstrate here that pureexperiment. Here we present a post-acquisition method to remove phase COSY spectra with the suppression of diagonal peaks the undesirable diagonal peaks by using singular value decomposican readily be obtained by the use of this proposed method,
