Attention is called to the photodynamic and thermodynamic properties of Periodic Group IIb elements, most notably Hg, as they relate to ultra-violet sensitization in organic chemical reactions. The energy levels of 6(1) P1 and 6(3) P1 resonance states and the high vapor pressure ((greater than 10(-3) mm) of the metal at temperatures as low as 293 K bring Hg with the range of bond dissociation energies in most organic molecules and many inorganics. These capabilities considered together with recent evidence for Hg emission as a regular part of volcanic and geothermal processes provide the basis for our proposal that Hg-sensitized ultraviolet photo-reactions may have played a significant part in abiogenetic organic synthesis on the primative earth.
请注意第IIb族元素（最显著的是汞）的光动力学和热力学性质，因为它们与有机化学反应中的紫外线敏化有关。6(1)P1和6(3)P1共振态的能级以及该金属在低至293K温度下的高蒸气压（大于10(-3)毫米）使汞处于大多数有机分子和许多无机分子的键解离能范围内。这些特性与最近关于汞排放是火山和地热过程常规组成部分的证据一起，为我们的提议提供了基础，即汞敏化的紫外光反应可能在原始地球上的非生物有机合成中发挥了重要作用。
