水分子在电场中的邻位和对位
Ortho and Para Molecules of Water in Electric Field
摘要:
用微扰理论方法分别计算了邻位水分子和对位水分子的斯塔克效应。在室温下,发现两种物质在电场中的能量变化相差30%。这意味着在非均匀电场中的邻位和对位水分子的排序。邻/仲水分离建议发生在固体表面上的蒸汽吸附和大规模的大气过程的过程中。
英文摘要:
Stark effect is calculated by the perturbation theory method separately for the ortho and para water molecules. At room temperature, a 30%-difference in the energy change is found for the two species put in electric field. This implies a sorting of the ortho and para water molecules in non-uniform electric fields. The ortho/para water separation is suggested to occur in the course of steam sorption on a solid surface and of large-scale atmospheric processes.
