The differential curve of spectral reflectance assumes a hypsochromic shift. 在光谱反射率曲线的微分图上显示出蓝移。
The rate of coordinate reaction between organic acid group and chromium could be evaluated by the rate of hypsochromic shift belonged to the long wave peak position of the mixed solution. 根据混合液长波特征吸收峰位的紫移速率大小可判断有机酸根与铬配位反应的快慢。
In high acid condition, the absorption maximum of porphyra-334 showed hypsochromic shift to shorter wavelength, the absorbance also decreased. 在强酸性条件下,MAAs化合物的最大吸收波长向低波长发生蓝移,吸光值降低。
