High‐quality multidimensional NMR spectra can be obtained from rapidly recorded non‐uniformly sampled (NUS) data. The inherent loss of the spectrum quality usually associated with NUS data is compensated by compressed sensing (CS); left spectrum: Nyquist–Shannon sampling, 22 h acquisition time, Fourier transform; right: CS non‐linear sampling, 8.5 h acquisition time, Ip norm minimization.
Ausgezeichnete mehrdimensionale NMR‐Spektren lassen sich aus rasch aufgezeichneten nichtuniform gesammelten (NUS) Daten erhalten. Der üblicherweise mit dem NUS‐Verfahren verbundene Verlust an Spektrenqualität wird durch komprimiertes Lesen (CS) kompensiert (linkes Spektrum: Nyquist‐Shannon‐Aufnahme, 22 h Akquisitionszeit, Fourier‐Transformation; rechts: nichtlineare CS‐Aufnahme, 8.5 h Akquisitionszeit, Ip‐Norm‐Minimierung).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
