NMR spectroscopy of polymers

One of the fundamental properties of atomic nuclei is nuclear spin. Each nucleus is characterized by a spin quantum number, I, and a magnetogyric ratio, y. There are 2/ + 1 nuclear spin states for each nucleus with energies given by  

One of the most useful nuclei to study in the analysis of hydrocarbon structure is ft is characterized by f = 1/2. Experimental techniques have been developed that allow isolated nuclei to be observed, unperturbed by interactions with the ubiquitous H nuclei. The energy difference between the m = 1/2 and m = -1/2 state is measured for all the nuclei in the sample. There are three types of carbon atom locations in the polypropylene molecule

Our research group has devoted itself to the investigation of the polymerization mechanism, especially in stereoregular polymerization, and to the control of polymer structure based on an understanding of the polymerization reaction. Well aware of the importance of detailed structural analysis of polymers in these studies, we have realized that NMR spectroscopy is the best tool for this purpose. This has encouraged us for a long time to commit to NMR spectroscopy of polymers. This chapter consists of several topics from our research work selected from the viewpoint described above.
