Abstract

'Elastic'neutron and x-ray diffraction patterns from crystals of Sb2S3 (minera1 stibnite) show that the crystals, while ordered along <010> (the chain axis) , are disordered about <010>. Extensive diffuse intensity perpendicular to <010> direction is observed. Inelastic scattering studies using 1.4Å neutrons did not lead to any soft TA modes with q in the (OkO) plane and polarised along <010>. A few longitudinal phonons along <010> are seen. Results from lattice dynamical calculations based on a rigid ion model (with covalent bonding included) are discussed in the context of these observations.
