Abstract
We have carefully determined the optical spectrum of K2Pt(CN)4Br0.3 3H2 O near the reflectivity edge. Our data reveal, in addition to the expected monotonic background, a broad peak in 2() above a threshold coinciding with the zero of 1() near 16 000 cm-1. We assign this band to indirect excitation of plasmons. Details of the excitation of plasmons are discussed with particular attention being paid to the problems presented by the one-dimensional character of the material. It is concluded that the electronic structure of this material cannot be adequately described by either a free-electron model or a one-band tight-binding model.
