Vibrational spectra and force constants of the tetrachloroaluminate, tetrabromoaluminate, and mixed bromochloroaluminate ions
Abstract
The i.r. and Raman spectra of the five ions [AlClnBr4–n]–(O ⩽n⩽ 4), which form an equilibrated mixture in solution have been determined and fitted to a unified Urey–Bradley force field.
