Self-consistent calculation of energy band structure of polysulphur nitride (SN)x, by the intersecting spheres model

It has been shown that the intersecting spheres model gives accurate results when applied to molecules and covalent three dimensional crystals. The model is here used for the calculation of the self consistent electronic structure of single chain of polysulphur nitride. We have also computed the electronic density of states which results in strict agreement with photoemission data.
