The article shows results of FT-IR and (1)H NMR study for azeotrope diethyl amine-acetone. Changes in chemical shifts and vibrational frequencies for pure diethyl amine, pure acetone and their azeotrope were obtained. The unit-structure of cluster has been suggested on the basis of mole ratio, boiling point depression for azeotrope of diethyl amine and acetone, and comparison between the spectra obtained by FT-IR and (1)H NMR techniques.
本文展示了傅里叶变换红外光谱（FT-IR）和氢核磁共振（¹H NMR）对二乙胺-丙酮共沸物的研究结果。获得了纯二乙胺、纯丙酮及其共沸物的化学位移和振动频率的变化。基于摩尔比、二乙胺与丙酮共沸物的沸点降低以及通过傅里叶变换红外光谱和氢核磁共振技术获得的光谱之间的比较，提出了簇的单元结构。
