Abstract
Studies of the nitrogen, deuteron and proton relaxation rates of liquid acetonitrile at various temperatures were carried out by pulsed NMR techniques. Reorientation of the methyl group about its symmetry axis is found to be approximately ten times faster than the reorientation of the nitrile group. Analysis of the data provides an example of a large room-temperature contribution to the intramolecular relaxation component by a spin rotation interaction. Previously sizable spin rotation interactions were considered to be insignificant for organic molecules at room temperature.
