Abstract
Five zone-centre phonons have been measured at low temperatures and for a range of concentrations in CsMg1-xCoxCl3. Three E2g modes and the A1g mode all exhibit the expected one-mode behaviour. A new theory is required to explain the unusual concentration dependence of the E1g phonon intensity, lineshape and polarisation.
