The 29Si MAS-NMR spectra of the 3C, 6H, and 15R silicon carbide polytypes are presented and interpreted. It is shown that there are a finite number of inequivalent silicon sites which are determined by the second- and third-order carbon and first- and second-order silicon coordinations. The spectra of any other SiC polytype may now be predicted.
