Acetonitrile-d 3 (CD 3 CN), an organo deutero compound, is an α-deuterated alkyl nitrile. Its synthesis from acetonitrile by base-catalyzed exchange with deuterium oxide has been reported. Its molecular rotational friction coefficient has been determined by measuring 2 H and 14 N nuclear magnetic resonance spin–lattice relaxation times. Its orientational dynamics in nanoporous glasses has been studied using optical Kerr effect spectroscopy.
