<正> 在以前的工作中,我们曾用Monte Carlo法对若干熔盐浴液的结构作计算机模拟,以研究其局部结构(local structure);与此相配合,我们选择一批熔盐溶液作激光Raman光谱研究。利用Raman光谱作为熔盐溶液中离子微环境的“探针”,本文报道我们对KNO_3-NaNO_2系的研究结果。Ах-тырский曾对此系的Raman光谱数据作过简短报道,但不足以探讨该系熔盐的局部结构。为此,我们测量了473—623K温度范围内的、各种配比的
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.
