Super-Resolution NMR Spectroscopy using the Intersection of Non-Redundant Information on Resonance Groups
The resolution of spectra is a major limitation in the application of Nuclear Magnetic Resonance (NMR) spectroscopy to large and complex molecular systems. In this report, we introduce a technique to enhance the resolution of NMR spectra beyond the intrinsic limitations of a spectrometer for a single spectrum by using the Intersection of Non-Redundant Information on Resonance Groups (INIR). With INIR, we reconstruct 900-MHz (21.1T) spectra from a 500-MHz (11.7T) NMR spectrometer, which compare favorably to experimental 900-MHz spectra. INIR holds promise in significantly enhancing the resolution of NMR spectra and in extending the size and complexity of molecules studied by NMR.
