The [Math Processing Error]1H water peak for both samples was recorded at 4.8 ppm, the spectrum of DMF is resolved, with [Math Processing Error]1H peaks at 2.93 ppm, 4.8 ppm, and 8.1 ppm, and the spectrum of methanol with [Math Processing Error]1H peaks at 4.8 ppm and 3.36 ppm....
The quadrupole splittings in the deuteron magnetic resonance spectrum of N,N-dimethylformamide- d 7 (DMF- d 7) oriented in a nematic phase have been measured in order to determine the quadrupole coupling constants. The elements of the order tensor, S ij's, necessary for the calculation of ...
