Infrared and Raman spectra are presented for salt solutions in N-methyl formamide and N,N'-dimethylformamide. Viscosities are reported for many of these solutions. Spectroscopic and viscosity data are also given for amide-salt solutions containing water. The three-component systems exhibit a hydrogen-bonding strength of water proton greater than amide proton, and an acceptor strength of Cl- greater than amide carbonyl oxygen greater than water oxygen. The salt cation is deduced by means of viscosity measurements to interact strongly with the amide carbonyl oxygen, even in the presence of appreciable quantities of water. Association of amides by hydrogen bonding through halide ions is also indicated.
本文给出了盐在N-甲基甲酰胺和N，N'-二甲基甲酰胺中的红外光谱和拉曼光谱。还报道了其中许多溶液的粘度。文中也给出了含有水的酰胺-盐溶液的光谱和粘度数据。三元体系显示，水质子的氢键强度大于酰胺质子，氯离子的受体强度大于酰胺羰基氧大于水氧。通过粘度测量推断，即使存在大量的水，盐阳离子也会与酰胺羰基氧强烈相互作用。还表明了酰胺通过卤离子形成氢键缔合。
