Non uniform sampling (NUS) allows multi-dimensional NMR data to be collected in a quarter or less of the traditional time. This is done by collecting only a fraction of the usual data and predicting the missing points. The data that is collected is defined by a sampling schedule and many different ways of creating these sampling schedules have been published. Several papers have reported that not all sampling schedules, even those created in the same way, produce the same quality spectra. Here, the spectra produced by different sampling schedules are compared and methods for assessing the quality of NUS spectra trialed.
