| 摘 要： | 采用向柠檬酸溶液中直接滴入四氯化钛的方法,实现了钛与柠檬酸的络合反应。向络合溶液中滴入氨水调节pH值,对特定的pH值溶液进行了拉曼光谱的测量,详细分析了(TiO)、(CO)等振动峰的归属。对络合离子基团的结构进行了模拟和光谱计算,所得到的结果和实验值符合得较好。

| Abstract: | TiCl4 was added slowly and under continuous stirring into citric acid solution to get coordination of Ti and citric acid.The pH of every solution sample was then adjusted to desired value by addition of ammonia.Raman spectrum was measured for each pH value.Ti-O and C-O stretch vibrations,which show direct relationship to coordination,were discussed and assigned.Also we performed calculation of the complex anion,and the result are agreement with experimental data. |
