Abstract

Pure-shift NMR enhances the spectral resolution, but the optimal resolutions can only be obtained at the cost of the acquisition time. We propose to accelerate the acquisition using optimised ’burst’ non-uniform sampling schemes[I. E. Ndukwe, A. Shchukina, K. Kazimierczuk, C. P. Butts,ChemComm, 2016, 52, 12769] and then reconstructing the undersampled signal mathematically. Here, we focus on the reliability of this reconstruction depending on the sampling scheme and present a workflow for the sampling optimization. It is ready to be implemented in routine measurements and yields a great improvement of the reconstruction in challenging cases.
