Reflection spectra of Bat-dGBiO~ over a wide spectral range are reported. For x lower than the critical value of ~ 0.35 contributions of free carders, interband transitions and midgap absorption processes are observed. The plasma frequency is small (< 0.1 eV) for all x below the insulator to metal t

On the basis of a simple model for the interatomic potential the lattice dynamics of Ba~\_xKxBiO3 were calculated. Some features of the structural phase diagram, the optical and neutron spectroscopy data can be explained in spite of the simplicity of the model. To compare the model calculations with
