Finally, the future role of 13C NMR spectroscopy for understanding complex mesogens is briefly mentioned.T NarasimhaswamyJournal of the Indian Institute of ScienceNarasimhaswamy, T. Solid-state 13C NMR Spectroscopy A Powerful Characterization Tool for Thermotropic Liquid Crystals. J. Indian Ins...
Meanwhile, CP/MAS-NMR spectroscopy has provided a method which gives narrow nuclear resonance lines from a solid-state specimen as well. Using this technique, it is now possible to produce spectra of "rare" nuclei (13C, 29Si, 15N etc.) which are resolved in terms of chemical structure. ...
