Si-29 magic-angle-spinning nuclear-magnetic resonance has been measured on spinel-type cubic silicon nitride (c-Si3N4). c-Si3N4 shows two Si-29 resonances at -50.0 +/-0.2 and -225.0 +/-0.2 ppm, corresponding to the tetrahedron SN4 and the octahedron SiN6, respectively. Integration of the spectrum gives SN4/SiN6 about one half that of the spinel structure. Ab initio self-consistent field Hartree-Fock molecular orbital calculations also indicate that the chemical shift for octahedral Si is more negative in nitride than in oxides.
