抄録

A study on 23Na nucleus in sodium nitrite, NaNO2, in the vicinity of phase transition temperatures was made using nuclear magnetic resonance. Simultaneous measurements of the spectrum and the dielectric constant εb made the one to one correspondence between them clear. The main results were as follows: A discontinuous jump of an electric field gradient tensor and thermal hysteresis were found at the transition temperature Tt. The curves of quadrupole splitting versus temperature show a small kink at the transition temperature Tn. Only one pair of satellite lines was observed in the sinusoidal antiferroelectric phase. The asymmetry parameter of the electric field gradient tensor, η, becomes zero at 0.3°∼0.4° below Tt in the cooling runs.
