Sažetak

The NMR spectrum is determined by interaction of resonating nuclei between the particles of the substance. These interactions depend on the spatial arrangement of the particles and their motion. Parameters characterizing interactions between the paramagnetic ions Me2+ (Me = Mn and Ni) and the protons of crystalline water in powdered MnSO4·1H2O and NiSO4·1H2O were derived from the temperature dependences on the second moment of the NMR spectra. The parameters characterizing the local magnetic field acting on the proton pairs were calculated and compared with those obtaind from the analysis of the shape of the NMR spectrum.
