利用 O-D 振动带的红外光谱数据定量研究了甲醇-d 分子中氘原子的亲核溶剂化。尽管单一溶剂溶液中甲醇-d 浓度变化，O-D 带的位置没有变化，而 O-D 峰面积与甲醇-d 浓度的一级成比例变化。从这些结果可以得出结论，O-D 带的面积对应于甲醇-d 溶剂化物的浓度。在由供电子能力存在显着差异的组分组成的二元溶剂体系中，在与单一溶剂体系中检测的组分相同的位置处观察到O-D峰的两个位置，并且每个O-D峰的面积随着体系的组成而变化。这些结果得出这样的结论：二元系统中每个组分的亲核溶剂化是竞争性且单独发生的……
The nucleophilic solvation to a deuterium atom in a methanol-d molecule has been quantitatively studied by using the infrared spectroscopic data of the O–D vibrational band. The position of the O–D band did not change in spite of the variation in the methanol-d concentration in solutions of a single solvent, whereas the area of the O–D peak changed in proportion to the first-order of the methanol-d concentration. From these results, it has been concluded that the area of the O–D band corresponds to the concentration of the methanol-d solvated. In a binary solvent system, which consisted of components with substantial differences in the electron-donating power, two positions of the O–D peak were observed at positions identical to those in the component examined in a single solvent system, and the area of each O–D peak changed with the composition of the system. These results led to the conclusion that the nucleophilic solvation of each component in the binary system took place competitively and individuall...
