Torsional vibrations of H₂O molecules in crystalline Li₂SO₄·H₂O

An Old Dog with New Tricks – Additions to the Cesium Lithium Chloride System: Cs3Li2Cl5 and the Hydrated Cs3LiCl4·4H2O

“…An FTIR ATR spectrum of Cs 3 LiCl 4 · 4H 2 O in the range of 400 to 4000 cm –1 is given in the SI Figure S1. Overlapping absorptions, assignable to Li–O vibrations and water modes, were found from 445 cm –1 to 695 cm –1 . Alkaline metal chloride vibrations, typically found around 714 ‐ 753 cm –1 , possibly overlapping with water torsion modes, were detected.…”

Water absorbed on the surface of the specimen is most likely causing absorptions detected at 2158 cm –1 .…”
