We have carried out studies of the effect of pressure on the following properties of the amorphous form and the two crystalline forms of germanium disulfide : the absorption edge in the near-UV, the refractive index in the near-IR, and the Raman spectrum. The results support the view that GeS2 glass is not a 3d-network glass akin to silica, but instead has lower network dimensionality.
