Two‐Dimensional Solid‐State NMR Spectroscopy: New Possibilities for the Investigation of the Structure and Dynamics of Solid Polymers [New Analytical Methods (38)]

Abstract NMR spectroscopy is an effective method not only for examining liquid samples but also for characterizing molecular sturcture, order and dynamics in amorphous and ordered solids. Recent developments in the area of solid‐state NMR spectroscopy span from model‐dependent studies of conventional one‐dimensional spectra to the more definitive two‐dimensional (2D) spectra which provide more specific information. For example, with 2D‐NMR spectroscopy it is possible to determine the orientational distribution functions of molecular segments in drawn polymers and to distinguish different mechanisms of complex molecular motions. Following an introduction to basic NMR spectroscopy, an overview of the current state‐of‐the‐art of 2D methods in solid‐state NMR spectroscopy is presented and demonstrated with selected examples.
