摘要
根据马吕斯定律，通过实验分析溶于有机溶剂酒石酸钾中的K2Cr2O7共振区的旋光色散（ORD），给出有机环境下使实验产生偏差的影响因子，并根据提出的单共振区ORD的正弦曲线分布模型，对多共振区采用正弦叠加法，拟合多共振区的ORD曲线，在波长350～680nm波段内，拟合曲线与实验曲线非常逼近，从而为解决共振区的ORD提供了一种准确简捷的方法，使共振区内的ORD能以具体的函数形式定量的表示出来，对分析共振区内的ORD有重要的理论参考价值。
In the resonant region, the optical rotatory dispersion（ORD） of K2 Cr2 O7 dissolved in an organic solvent is analysed experimentally. Based on Malus law,a factor is proposed to eliminate the effect of organic environment. The optical rotatory dispersion curve in multi-resonant region is fitted by sine wave superposition. The fitting curve approximates to the experimental data very well among the region of wavelength 350 nm- 680 nm. This method can achieve accuracy, convenience. It is possible to express the ORD curves in resonant region in form of functions concretely. So the method is valuable in the area of analysing ORD in resonant region.
