¹H, ²H and ¹⁴N nuclear magnetic resonance relaxation study of the acetonitrile-chloroform liquid system

Abstract

2H and 14N spin-lattice relaxation times for the CD3CN and CDCl3 molecules in the CD3CN-CDCl3 liquid system have been determined at temperatures between 250 and 315 K. Analyses of these data led to the determination of rotational diffusion coefficients about the C3 symmetry axis (D∥) and around the axes perpendicular to the symmetry axis (D⊥). Anisotropy of the rotational motions (D∥/D⊥) of CD3CN increases upon addition of CDCl3 to CD3CN liquids and reaches maxima at the mole fraction of CDCl3[χ(CDCl3)] = 0.8. Slowing down of the rotational motions of CDCl3 is also observed, and reaches minima at χ(CDCl3) = 0.6-0.7.
