Area of Science:

  • Physical Chemistry
  • Biophysics
  • Materials Science

Background:

  • Water's unique properties are crucial in biological and chemical systems.
  • Understanding molecular interactions is key to various scientific fields.

Purpose of the Study:

  • To investigate the influence of water molecule spin states (ortho and para) on absorption kinetics.
  • To analyze the differential binding of water spin isomers with lyophilized DNA, lysozyme, and inorganic sorbents.

Main Methods:

  • Studying the absorption of ortho and para water vapor.
  • Analyzing sorption kinetics on different preparations (DNA, lysozyme, inorganic sorbents).

Main Results:

  • Absorption rates of ortho and para water isomers were observed to differ noticeably.
  • Para-water isomer binding was distinctly faster than ortho-water isomer binding across all tested preparations.
  • The observed differences in sorption kinetics are attributed to the distinct quantum statistics of water spin isomers.

Conclusions:

  • The spin state of water molecules plays a critical role in their adsorption behavior.
  • Differences in physico-chemical properties between ortho and para water arise from their quantum statistics.
  • This research opens avenues for exploring the role of water spin states in physics, chemistry, biology, and medicine.
