摘要/Abstract

摘要： 固体甲酸铀酰化合物在可见或紫外光照下可以发生光解。Claudel等的研究结果表明,这类光解反应是由于分子被激发到电子激发单重态S₁所引起的。最近徐葆裕等发现在共振的强红外激光场作用下,单结晶水甲酸铀酰也能发生光解。本文研究了一系列固体甲酸铀酰化合物的红外吸收光谱以及碱式甲酸铀酰的红外光解反应。

Abstract: Aseries of Solid uranyl formates ere prepared and their infrared absorption spectra were investigated. It was found that the anti-symmetric vibration frequencies of uranyl group,vα,for these compounds were in the range of 912-952 cm^-1,and the vα absorption peaks were single-shaped for some uranyl formate double salts. According to above vαabsorption spectra,the decomposition of basic uranyl formate was also investigated by using TEA-CO₂laser. The experimental results showed that the photodecomposition reaction could take place only under intense irradiation at the frequency resonant with the vα of uranyl group.
