Abstract

The magic angle solid‐state NMR spectra of SnO~2~ and SnO were recorded and analysed. The chemical shift tensor anisotropy is much smaller for SnO~2~ (136 ppm) than for SnO (975 ppm). Simple calculations suggest that the latter is mainly due to the asymmetry in the valence electron cloud of the tin atom in SnO. An Snο£ΏSn indirect coupling of 8300 Hz was found in SnO, indicating the possibility of Sn 5s orbitals at the top of the valence band of SnO.
