THE VIBRATIONAL SPECTRUM AND STRUCTURE OF THE $ICl_{2}+ION$

Abstract

The Raman and infrared spectra of $ICl_{2}^{+}$ are presented as observed in the complexes $SbICl_{8}$ and $AIICI_{6}$. All three fundamentals were observed and, in agreement with X-ray diffraction observations, the spectrum shows that $ICl_{2}^{-}$ is bent ($C_{2v}$) and the complexes are ionic. The spectra and calculated force constants are compared with those of $ClF_{2}^{+}$.
