Abstract
Infrared and Raman spectra of CsCl·13H3OHCl2and CsBr·13H3OHBr2 have been measured in the 50–4000‐ cm−1 region. The spectra show the bands expected for the oxonium ion plus bands due to the XHX ion. The XHX ions are in a symmetrical environment, and a consistent interpretation of the spectra suggests that the XHX ions have a centrosymmetric structure in these salts.
