Мы не чувствуем движения Земли, но, допустив ее неподвижность, мы приходим к бессмыслице; допустив же движение, которого мы не чувствуем, мы приходим к законам.

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.
