Spin states of para-water and ortho-water molecule in gas and liquid phases

TL;DR

This paper investigates the spin states of water molecules in gas and liquid phases to understand the long-term behavior of water spin isomers, using quantum models and surface interaction assumptions.

Contribution

It introduces a model where water molecules change from pure to mixed spin states upon interacting with surfaces, applying quantum information concepts.

Findings

Water spin states vary between gas and liquid phases.

Surface interactions induce mixed spin states.

The model explains long-term spin isomer behavior.

Abstract

Spin degrees of freedom of water molecule in gas and liquid state were investigated in order to provide a reasonable answer about the unsolved problem of a long-term behavior of water spin isomers. The approach used involves an assumption that molecules change their spin state from a pure state to a mixed one when they interact with some sorts of adsorbent surface. Some models and conceptions of the quantum information processing were used.
