Applications of two-dimensional NMR spectroscopy to oriented molecules

Abstract

Two-dimensional (2D) NMR spectroscopy has proved exceedingly useful in the study of oriented molecules. In this article the applications of this technique to the study of molecules oriented in liquid crystalline solvent are reviewed. The main appliations have been, (a) in simplification of NMR spectra by symmetry filtering, multiple quantum filtering and multiple quantum 2D spectroscopy, (b) in enhancing information content of spectra by spin-echo and correlated 2D spectroscopies, and (c) in the study of multiple quantum relaxation rates by 2D spectroscopy.
