The authors carried out relativistic and quasirelativistic calculations of the band structure of Rh, Pd and Pt, analyzed the influence of SO interaction on formation of the spectra of those materials and evaluated the possibility of excluding it. The calculations have been performed in the method of Green's function realized in with a model potential. The values of the lattice constant and screening parameters are given. In both modifications the energy terms of the six valence bands were calculated at 86 points of 1/48 part of the Brillouin zone. The results for high symmetry points are given.
