%X The Raman spectra of molten KNO_3-NaNO_2 solution at 473--623 K have beenmeasured and the regularity of the shape of spectra investigated. The symmetrical stretching frequency peak v_1 of NO_3- or NO_2- becomes broaden as the temperature increases or the concentra-tion of NO_3- or NO_2- ions in KNO_3NaNO_3 mixture decreases. The results have been discussedbased on the view-point of a theoretical model obtained in previous work.
