## Abstract Information about the orderβdisorder transition of NaNO~2~ is obtained from the temperature dependence of the optical nonlinear susceptibility Ο^(2)^. The decrease of Ο^(2)^(__T__) in the ferroelectric phase can be related to increasing rotational motion of the NOβions. While Ο^(2)^ ind

The passivation of nickel in molten alkaline nitrites and the electrochemical dissolution of passive nickel have been studied at temperatures ranging from 234-306Β°C. The passivation potential is established both in the potentiostatic E/Z curvy and in the galvanostatic anodic potential build-up. The
## Abstract Raman spectra of oriented sodium nitrite single crystals are reported. Halfβwidths, peak frequencies and band shapes change when the temperature is varied from 30 to 513 K. Resolution of the Raman bands of the symmetric NO vibrations into contributions from ordered and disordered positi
