将振动圆二色性（VCD）技术应用于碳水化合物，得到了一个糖苷特征VCD带，命名为“糖苷带”。用同位素取代的方法证实了d系碳水化合物的这种振动与碳水化合物的异构体构型有关。该波段在1145 cm-1附近被定义为一个负的、尖锐的、强烈的VCD波段，由具有轴向α -糖苷键的d糖在4C1构象中表现出来。作为该波段的应用，研究了麦芽糖-纤维素二糖混合物的VCD研究和淀粉葡糖苷酶反应的监测。
The vibrational circular dichroism (VCD) technique was applied to carbohydrates and produced a glycoside characteristic VCD band, which was named the "glycoside band." It confirmed that this vibration was related to anomeric configurations of carbohydrates in the case of the d-series by means of isotope substitution. This band is defined as a negative, sharp, and intense VCD band at around 1145 cm-1, exhibited by d-sugars with an axial alpha-glycosidic linkage in the 4C1 conformation. As applications of this band, the VCD studies of the maltose-cellobiose mixture and the monitoring of the amyloglucosidase reaction were examined.
