13C chemical shielding anisotropy in the solid phases of CH313CN

The principal elements of the axially symmetric nitrile 13C chemical shift tensor, and the CN bond distance of solid CH3CN have been determined from both static and sample spinning NMR experiments at 78 and 140 K. The spectra show no significant differences between the α and β forms of the solid though a large temperature coefficient is observed for both the isotropic chemical shift, σ, and the 14N nuclear electric quadrupole interactions as seen through the carbon-nitrogen dibole interaction.
