C-13 NMR and dielectric relaxation studies of methanol plus nitrile systems

C-13 NMR studies for both spin-lattice relaxation time (T-1) and chemical shifts were obtained for two systems namely methanol+acetonitrile and methanol+acrylonitrile. The dielectric dispersion data was also obtained for these systems. The C-13 NMR and dielectric dispersion data with a view to understand the conformation of these systems and also to understand the basic mechanisms of relaxation in the same have been presented. A correlation between the rotational correlation time from NMR and the dielectric relaxation time for the two systems have been reported. The confirmation of the ring-like conformer for methanol+acetonitrile system using C-13 NMR chemical shift data.
