Hardcover Abstract: Nuclear Quadrupole Resonance Spectroscopy has become a standard method for structural research in molecular and solid state physics as well as for different branches of chemistry. The volumes cover data for more than 8,000 substances in the solid state. Data for free molecules have been published in volumes II/14 and II/15 of the New Series. The tables are arranged according to the atomic number of the elements.

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。
