本文报道了其他作者在几篇文章中提出的用吸附法富集H_2O核自旋异构体的实验数据。我们无法观察到异构体的任何富集。结果表明，水的邻位异构体和帕拉异构体的吸附特性差异不大。分析了分子邻位和帕拉自旋态的分子内混合引起的H2O自旋异构体的弛豫，以及与顺磁氧分子碰撞引起的弛豫。
Experimental data on the enrichment of H2O nuclear spin isomers by means of adsorption, as suggested in several works by other authors, are reported. We were unable to observe any enrichment of isomers. The conclusion was drawn that the adsorption characteristics of water ortho and para isomers were insignificantly different. An analysis of the relaxation of H2O spin isomers induced by the intramolecular mixing of the molecular ortho and para spin states and caused by collisions with paramagnetic oxygen molecules was performed.
