Notizen:
The study of polymers by nuclear magnetic resonance spectroscopy has made tremendous advances in the last few years, not only with the development of superconducting solenoid magnets with increasing field strength, permitting the resolution of increasingly fine structural detail and greater sensitivity, but also in the development of new techniques. Among these is the use of two-dimensional (2D) NMR, permitting easier and more rigorous assignment of resonances. Another important advance has been the development of means to observe high resolution spectra in the solid state, through high-power dipolar decoupling, cross-polarization, and magic angle spinning. A third significant development is that of deuterium quad-rupole echo spectroscopy, permitting the study of chain dynamics in the solid state with unprecedented power and precision.
