摘要: Infrared absorption spectra of ice were obtained at 4, 60, 100, 140, 160, and 240 K to make spectroscopic observations hydrogen ordering low temperatures. A broad peak observed around 850 cm–1 (11.7 μm) was derived from libration water molecules. The width notably narrower temperatures less than 140 K. decrease in the occurring accordance with formation ordered arrangements atoms suggested incoherent inelastic neutron-scattering studies. These results are consistent atoms. existence hydrogen-ordered space is subject continuing astronomical debate. Our demonstrate that detectable using infrared telescopes planetary exploration.
