研究了八水合三硫酸镉晶体在空气中受热脱水过程的傅立叶变换拉曼光谱。结果表明,受热脱水过程中硫酸根离子与镉离子之间的配位形式发生了变化。其中,硫酸根离子的2ν和ν3谱带的变化显示出在3CdSO4.8H2O转变为CdSO4.H2O的过程中,硫酸根离子与镉离子之间的配位形式从单齿配位转变为了双齿配位。
Fourier transform Raman spectroscopy of the dehydration process of cadmium trisulfate octahydrate in air was studied. The results show that the coordination between sulfate ions and cadmium ions changes during the dehydration process. Among them, the changes of the 2ν and ν3 bands of sulfate ions show that the transition between the sulfate ion and the cadmium ion shifts from monodentate to bidentate during the conversion of 3CdSO4.8H2O into CdSO4 · H2O Bit.
