Abstract

Abstract: A strong case exists for the introduction of burst non‐uniform sampling (NUS) in the direct dimension of NMR spectroscopy experiments. The resulting gaps in the NMR free induction decay can reduce the power demands of long experiments (by switching off broadband decoupling for example) and/or be used to introduce additional pulses (to refocus homonuclear coupling, for example). The final EXtended ACquisition Time (EXACT) spectra are accessed by algorithmic reconstruction of the missing data points and can provide higher resolution in the direct dimension than is achievable with existing non‐NUS methods. Abstract : Just to be EXACT : Burst non‐uniform sampling in the direct dimension of some NMR experiments, followed by algorithmic reconstruction of the missing data points, allows Extended Acquisition Times (EXACT) to provide higher resolution NMR data than is achievable for existing methods.
