本文主要介绍在4000—400cm~(-1)范围内用天然水、99.886 mol.%重水配制的不同浓度的H_2O-HDO—D_2O混合物体系,含氘10.0%(原子分数)的H_2O—HTO-T_2O混合物体系及含氘41.2%(原子分数)的D_2O-DTO-T_2O混合物体系;研究了液态H_2O、HDO、D_2O、HTO、DTO和T_2O的红外吸收光谱,并用经验规律计算了氘水的红外吸收峰的波数值。由实验得到的光谱吸收峰位置与文献值和计算值相一致。
This paper mainly introduces the H_2O-HDO-D_2O mixture system with different concentrations of natural water and 99.886 mol% of heavy water in the range of 4000-400 cm -1, and the H_2O-HTO-T_2O with 10.0% of deuterium (atomic fraction) Mixture system and D_2O-DTO-T_2O mixture system containing 41.2% deuterium (atomic fraction). The infrared absorption spectra of liquid H_2O, HDO, D_2O, HTO, DTO and T_2O were studied and the infrared absorption peak Wave value. The spectral absorption peak position obtained by experiment is consistent with the literature value and the calculated value.
