Accurate measurements have been made of the 23 Na nuclear magnetic resonance spectrum of sodium nitrate single crystals from -190 176 C to 300 176 C in an applied magnetic field of 6000 Oe The nuclear electric quadrupole coupling constant has a magnitude which is convenient for the separation of first- and second-order shifts of the resonance lin...
Add the sodium nitrite solution dropwise to ensure that the temperature stays as low as possible Do not let the temperature rise above 5 176 C, as the sensitive phenyldiazonium chloride would decompose If the temperature gets too high, brown-orange nitrogen dioxide gas will be released Keep the magnetic stirrer stirring and use the salt-ice bath for cooling throughout the entire addition...
Abstract The nuclear quadrupole resonance of 14 N in sodium nitrite was observed in a temperature range of 77-400 176 K From the observed quadrupole coupling constant and the asymmetry parameter, the field gradients were calculated along the principal ax...
