摘　　要：通过对酒石酸钾为溶剂的K2C r2O7溶液在不同浓度下的圆二向色性进行测试,显示出该溶液对波长在500nm-700nm范围内的光表现出明显的圆二向色性,而且其圆二向色性随溶液浓度的降低而减弱,同时也发现该溶液的最大吸收波长出现红移现象,波长漂移量可达5.5nm。Using KC4H5O6 as solvent, the circular dichroism of K2Cr2O7 solution was measured by optical test apparatus. Its circular dichroism was observed obviously at the wavelength from 500nm to 700nm . As the density of the solution decreasing, its circular dichroism becomes weak. The maximal absorption wavelength of K2Cr2O7 solution also appears red-shift phenomena, the excursion of wavelength can be 5.5nm.
