Hardcover Abstract: Volume II/25 is a supplemented and revised edition of the preceding volumes II/7, II/15, II/21 and II/23 containing up to date information on inorganic and organic polyatomic molecules. All experimental methods for the determination of quantitative structural data of free molecules have been considered: microwave, infrared, Raman, electronic and photoelectron spectroscopy as well as electron diffraction. The data obtained by these methods have been critically evaluated and compiled. They are presented separately for each molecule, together with a schematic figure of the structure and the original literature.

- 方法一:直接法以钽粉和氟为原料制备五氟化钽：以蒙乃尔合金或镍制的L型管作反应管，首先从管的一端抽真空，以除去管内的空气和水分，然后在该端加入金属钽粉，再将此端放入电炉中，将另一端放人半融化的干冰中，控制电炉使温度升至300℃，这时向反应管中通入氟气，经反应后即在干冰处生成凝固的固体五氟化钽粉末。反应产物经真空蒸馏，在-10℃收集得99％五氟化钽。在高真空的条件下，于90～100℃温度下升华，即得精制五氟化钽。产品必须贮存于干燥的硼硅酸玻璃的容器中并密封。 合成法以五氯化钽和无水氢氟酸为原料制备五氟化钽：在室温下，五氯化钽和无水氢氟酸反应，反应后经冷凝、过滤分离即得固体五氟化钽，然后在真空下升华，即制得精制五氟化钽。
