The influence of polytypic structures on the solid-state C-13 NMR spectra of n-alkanes
Two polytypes for the monoclinic (Moll) modification of n-hexatriacontane (n-C36H74), single-layered structure Mon and double-layered structure Orth 11, were studied by means of the solid-state CP/MAS C-13 NMR spectroscopy. The terminal methyl carbon showed clear differences in the chemical shift as well as spin-lattice relaxation time (T-1) between Mon and Orth 11, in contrast to no marked difference for the other carbons.
