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
