| 摘 要： | Cr交换丝光沸石在氢气氛中强烈还原并冷却后,出现了一个各向同性的EPR信号,g值2.003,△HPP 13.4 gauss.采用EHMO方法计算了各种可能模型化合物的g值,结果建议这一信号对应Cr(V)与H2分子形成的络合物。

| Abstract: | Cr exchanged mordenitc displayed a new isotropic EPR signal after strong reduction in hydrogen atmosphere, with g=2.003 and △HPP=13. 4 gauss. The EHMO calculations were performed for several models and the results support the assertion that the new signal is responsible for a Cr (V) complex formed with hydrogen molecules. |
