The Sensitivity of Non-Uniform Sampling NMR

David Rovnyak, Department of Chemistry, Bucknell University

Abstract: The advent of multi-dimensional NMR, grounded in the use of the Fast-Fourier Transform (FFT) algorithm, ignited decades of innovation and discovery in studying the structures and dynamics of molecules. A modified method for acquiring multi-dimensional NMR data, termed non-uniform sampling (NUS), can informally be described as “skipping” certain data points. Although offering several advantages, NUS data can not take advantage of the FFT and the theorems associated with its use. We have been developing exact analytic expressions, with extensive experimental verification, that place some of the advantages of NUS methods on stronger theoretical foundations. We recently solved the exact sensitivity of NUS-NMR of decaying signals, showing that NUS leads to significant and predictable sensitivity enhancements that enable new science. In particular: NUS can simultaneously improve resolution and sensitivity, a statement that cannot be applied to conventional data acquisition. The theory also indicates road maps for further optimizations of NUS resolution and sensitivity that are currently being developed in our lab.
