【摘要】 fac-[Rh（NH₃）₃Cl₃]属C_3v群,mer-[Rh（NH₃）₃Cl₃]属C_2v群,就此而论,前者的红外谱图应比后者简单。但事实恰相反。本文讨论fac-[Rh（NH₃）₃Cl₃]红外谱图的部份异常现象。更多还原

【Abstract】 The 1400cm^-1 absorption band of fac-[Rh（NH₃）₃Cl₃] Infrared Spectrum haven’t been discussed before. After we analysed our experimental data and other people’s Infrared Spectra, it is concluded that in solid state there are three hydrogen bonds between two adjacent fac-[Rh（NH₃）₃Cl₃] molecules, these bonds enable two adjacent fac-[Rh（NH₃）₃Cl₃] molecules to approach each other more closely, then the vibrations of ligand NH₃ are heavily affected, and 1400cm^-1 absorption band takes place.更多还原
