The infrared spectra of polyoxometalates are addressed. The vibration frequencies of some synthesized polyoxometalates in recent years are emphasized. It was found that the infrared spectra of polyoxometalates result from stretch vibration frequency of the metal-oxygen, and 1 100-400 cm(-1) is the region of the characteristic absorption peak. The infrared spectrum contains information about the symmetry of polyoxoanion as well. As an analytical means, the infrared spectrum can be used to distinguish heteropolyanion and provide information on structure.
本文探讨了多金属氧酸盐的红外光谱。重点介绍了近年来一些合成多金属氧酸盐的振动频率。研究发现，多金属氧酸盐的红外光谱源于金属 - 氧的伸缩振动频率，1100 - 400 cm⁻¹ 是特征吸收峰所在区域。红外光谱还包含有关多氧阴离子对称性的信息。作为一种分析手段，红外光谱可用于区分杂多阴离子并提供结构信息。
