Method for increasing resolution in two-dimensional solid-state NMR heteronuclear correlation spectra.

摘要

A new RF pulse sequence is applied to selected nuclei (<1><3>C) in the evolution period (<1>H EVOLUTION) of a 2D NMR heteronuclear correlation experiment to more effectively suppress heteronuclear interactions. The new pulse sequence is designed to be effective with the existing BLEW-12 pulse sequence (BLEW-12) so that both homonuclear and heteronuclear interactions are suppressed. In addition, the new pulse sequence effectively suppresses homonuclear interactions so that it can be used with a variety of nuclear species. <IMAGE>
