Abstract
Raman spectra of the ferroelectric sodium nitrite are recorded over a wide spectral range at different temperatures, including the ferroelectric phase transition interval. The room-temperature Raman spectrum reveals the overdamped А1(z) soft mode which is attributed to the ferroelectric phase transition.
