High-resolution NMR spectroscopy in inhomogeneous B-0 and B-1 fields by two-dimensional correlation
Recently, there has been much interest in methods for obtaining high-resolution NMR spectra in inhomogeneous B-0 and B-1 fields and in their application to so-called 'ex situ' spectroscopy, where the sample and magnet/probe assembly are spatially separated. Here we discuss the implementation of the well-known two-dimensional nutation experiment as a method for correlating B-0 and B-1 inhomogeneities and, hence, achieving a high-resolution NMR spectrum. The advantages of this approach lie in its simplicity, its spatial ('depth') resolution, and in its not requiring a linear correlation of fields, i.e., B-1 = alphaB(0) + k, across the sample.
