Spin‐modifyied water : Adsorption isotherms are measured separately for ortho ‐ and para ‐water on a hydrophobic adsorbent (see picture; adsorbed molecules n O and n P as functions of partial pressures p O and p P ) . In a closed volume filled with adsorbent the equilibrium gas‐phase ortho : para ratio deviates noticeably from the statistical 3:1 in favor of the ortho component. Correspondingly, adsorbed water is formally para ‐enriched.
