| 中文摘要: |
| 通过对酒石酸钾为溶剂的K2Cr2O7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. |
| 英文摘要: |
| Using KC_4H_5O_6 as solvent,the circular dichroism of K_2Cr_2O_7 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 K_2Cr_2O_7 solution also appears red-shift phenomena,the excursion of wavelength can be 5.5nm. |
