用Raman和FT IR光谱实验技术对Cs(NTO)·H2O配合物水溶液的振动光谱进行了研究,从单晶结构角度说明了配合体的原子与Cs离子之间的配合键;量子化学计算结果表明配合键的性质主要属于静电吸引作用.该配合物饱和水溶液与晶体的振动光谱峰吻合.证明水溶液中的振动光谱可以用晶体中键的形成来说明光谱峰归属.
The vibrational spectra of Cs (NTO) · H2O complex aqueous solution were studied by Raman and FT IR spectroscopy. The coordination bond between the ligand and Cs ion was described from the viewpoint of single crystal structure. Quantum chemical calculations showed that The nature of the coordination bond is mainly electrostatic attraction. The saturated aqueous solution of the complex is consistent with the vibrational peak of the crystal. It is proved that the vibration peak in aqueous solution can be explained by the formation of the central bond.
