New developments in nuclear magnetic resonance using noise spectroscopy

In the 30 years since Ernst and Kaiser introduced the idea of incoherent ra diation fields and their application to NMR spectroscopy, relatively few re searchers have exploited the advantages of noise spectroscopy. Some recent applications of one-dimensional noise spectroscopy in NMR are presented whi ch display a versatility which commonly is not appreciated. Excitation sche mes are discussed which demonstrate both broadband and narrowband features, and demonstrate both theoretically and experimentally how noise spectrosco py allows for the observation of distortion-free broadline spectra in solid s which may not be amenable to techniques more traditionally used in pulsed NMR experiments. It is argued that these applications of noise spectroscop y deserve a more common place in the experimentalist's arsenal.
