中文摘要：

无机含氧酸盐含多个σ成键轨道和π键结构,具有明显的红外-拉曼光谱特征.该文对常见的硫酸盐、硝酸盐、碳酸盐及磷酸盐进行红外和拉曼光谱测试.结果表明：同一状态下,受金属阳离子的影响,同一酸根的拉曼特征谱带均随原子序数的增大向低波数位移;酸根中非金属元素与氧原子之间的电子云分布的不均等性在红外光谱中有明显体现.以一价金属阳离子的硝酸盐为例,对其4种简正振动模式进行红外和拉曼谱带归属,研究了一价金属阳离子对酸根结构的影响.

英文摘要：

Inorganic oxysalts have multiple bonding orbits and π bond structure, and with the evident characteristic of infrared and Raman spectra. General sulfates, nitrates, carbonates and phosphates have been measured by the infrared and Raman spectra. The results show that the characteristic bands of Raman spectra for the acid radical shift to lower wavenumber with the increase of the atomic number under the same condition which affected by the metal cation. And the unequal character of the distribution of electron cloud between non-metallic element and oxygen atom in acid radical was obviously displayed in IR spectrum. With the nitrate as an example, the authors have studied the IR and Roman spectra of the four normal vibrations. And how the structure of nitrate ions influenced by univalent metallic cations is also discussed.
