✦ Synopsis

The principal elements of the axially symmetric nitrile ~3C 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 a and /3 forms of the solid though a large temperature coefficient is observed for both the isotropic chemical shift, ~, and the ~4N nuclear electric quadrupole interactions as seen through the carbon-nitrogen dipole interaction.
