What is non-uniform sampling NMR?

Non-Uniform Sampling (NUS) is an acquisition method for NMR experiments with two or more dimensions that skips some fraction of data that would usually be measured. ^1–3. NUS is already widely familiar in biomolecular NMR, and can benefit other NMR applications as well.

Why is non-uniform sampling?

It has been shown in previous works that non-uniform sampling and processing is a better scheme than the uniform sampling to sample and process low activity signals. Non-uniform sampling technique generates fewer samples, which means less data to process and lower power consumption.
