The work "entails one of the earliest, and arguably cleverest, concepts put forward for narrowing wide lines in NMR--to combat one broadening with another broadening. The technique "begins with the realization that in several kinds of heterogeneous, disordered solids--where NMR peaks tend to be particularly ill-defined because of dispersions arising in chemical shifts--the broadening exhibited by any particular chemical site parallels in a nearly one-to-one fashion the broadening exhibited by its nearest neighbor. Rather than attempting to average out these incapacitating broadenings. Authors demonstrate that they can actually be exploited for achieving an increase in spectral resolution."
