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/24B contains an introduction and tables of rotational and centrifugal distortion constants of asymmetric-top molecules, i.e. data which roughly specifies the frequencies of the rotational transitions of these types of rotors.

  • 毒性分级:中毒
  • 硫化氢:氢硫酸是硫化氢的水溶液，硫化氢是硫的氢化物，化学式为H2S。一种无色、有恶臭味(臭鸡蛋味)的剧毒气体。能溶于水和乙醇，比重为1.1906。熔点-85.5°C，沸点-60.4°C，临界温度100.4°C，临界压力90.06×105帕。自燃点为260°C，具有可燃性，遇火星能引起爆炸燃烧，与空气相混时，能引发爆炸，爆炸极限为4%～44%(体积)。能与多种离子起化学作用，生成不溶于水的硫化物，能使铜、银表面变黑。广泛存在于金属冶炼、天然气 、盐酸和硫酸等的制造工业中。在制造硫酸盐纸浆、人造丝、人造棉、橡胶、二硫化碳等各种硫化物时，常有硫化氢气体排出。在一些化学反应中，含硫化合物不稳定也会分解出硫化氢，如：炼焦、精制石油及金属冶炼中，硫化氢作为一种常规废气，极易泄漏到空气中。硫化染料分解也可放出硫化氢气体。 硫化氢在水中电离，是个二元弱酸， 称为氢硫酸： 图1：硫化氢在水中电离生产氢硫酸 在空气中， 氢硫酸能被氧逐渐氧化， 析出硫磺而变混浊故必须在使用前临时配制。硫化氢化学性质不稳定，加热时会分解为氢和硫。在空气中燃烧， 生成水和二氧化硫。在不足的空气中燃烧， 可得到单质硫。硫化氢中的硫易于给出电子， 所以它是一种很好的还原剂。如在酸性介质中， 它能将Fe3+还原成Fe2+， 将Br2还原成Br-， 将MnO-4还原为Mn2+，将Cr2O2-7还原成Cr3+，将HNO3还原成NO2等，而硫化氢则被氧化成单质硫或亚硫酸盐或硫酸盐。在潮湿的空气中硫化氢和SO2反应生成单质硫 (歧化反应的逆反应)。硫化氢能使银、铜等制品表面变黑， 与许多金属离子作用， 生成不溶于水或酸的硫化物沉淀。在实验室中常用于分离、鉴定金属离子。硫化氢在实验室中常用FeS与稀盐酸作用来制取。氢与硫只在加热时才反应生成硫化氢。
