Hardcover Abstract: Volume II/24 presents the spectroscopic data on diamagnetic and paramagnetic molecules as well as on molecular ions and radicals up to date considering the publications up to and partly including 1997. The spectroscopic information collected in this volume has been obtained principally from gas phase microwave measurements. Volume II/24 is a supplement to volumes II/4, II/6, II/14, and II/19 and is planned to appear in five subvolumes, the last of which will contain the substance index taking into account all molecules worked at since 1967 in the volumes mentioned and will provide cross references to and between all tables of these. The present subvolume II/24A contains the general introduction and tables of rotational and centrifugal distortion constants of diamagnetic diatomic, linear and symmetric-top molecules, i.e. data which roughly specifies the frequencies of the rotational transitions of these types of rotors.

  • 常温常压下状态:三氧化硫又称硫酸酐，硫的高价氧化物,硫酸工业的产品之一。常压和室温下为无色液体，沸点44.8℃。在大气中强烈发烟，形成难以沉降的硫酸雾。与水发生异常剧烈的反应，生成硫酸，并伴有酸雾，同时释出大量热。三氧化硫溶解于 100％硫酸中生成发烟硫酸。固态三氧化硫有熔点分别为16.86℃、30.4℃与 62.2℃的三种形态，后两者为高分子量的三氧化硫聚合物，前者则为单分子体与三聚体的混合物。降低温度、存在微量水或硫酸时能促进液态三氧化硫的聚合。当熔化聚合态三氧化硫时，因在熔化前已产生较高蒸气压，有可能发生爆炸。

  • 爆炸物危险特性:遇水产生高热爆炸
  • 常规方法:包装参见液体二氧化硫。稳定的液体三氧化硫输送技术与高浓度发烟硫酸相同，要避免进入水分防止聚合。在生产、贮存和处理时，必须完全密闭。贮槽、装槽等设备的排气管必须通过一个酸洗涤塔，防止大气水分渗入和三氧化硫溢出。对于凝固点为16.8℃的液体三氧化硫，在加工阶段、成品贮槽和散装供应槽内都应保温在30℃。只有对那些允许固化的工厂，才允许用桶装贮藏。装液体三氧化硫的容器，绝对不能用水清洗，必须用浓硫酸来溶解三氧化硫的固体沉积物。 失火时，可用二氧化碳灭火器

  • 三氧化硫与水反应:跟二氧化硫相类似的，三氧化硫也是一种酸性氧化物，具有酸性氧化物的通性，它与水反应生成硫酸，所以我们也把它称为“硫酐”。 在三氧化硫里最重要的性质就是它与水的反应，因为它与水反应
