Abstract

A spin selectivity of processes occurring in vapor above the surface of boiling water has been detected for the first time, to the best of our knowledge. A tunable diode laser operated at 1.35 microns was used to analyze the relative content of Н₂О spin isomers in water vapor. A significant increase in the H₂O ortho-/para-molecule ratio (5:1) compared to the statistically stable state (3:1) was observed at 80-90°C. A possible mechanism of the phenomenon could be associated with the depletion of vapor by the para-H₂O isomer due to its higher activity in condensation and formation of water microdrops.

H2O同分异构体在沸水以上蒸汽中的自旋选择性大于5:1。

据我们所知，在沸水表面以上的蒸汽中发生的过程的自旋选择性首次被探测到。利用波长为1.35微米的可调谐二极管激光器分析了水蒸汽中Н2О自旋异构体的相对含量。在80-90°C时，与统计稳定状态（3:1）相比，H2O的邻位/对分子比例（5:1）显著增加。这种现象的一种可能的机制可能与对水异构体由于其较高的凝结和形成水微滴的活性而消耗蒸汽有关。

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
