Symmetry of localized orbitals in molecules with spin-orbit interaction

We construct representations of crystallographic point groups induced by double-valued irreducible representations of their local subgroups. Using the tetrahedral molecule Bi₄ as an example, we illustrate application of the results obtained to the symmetry analysis of localized molecular orbitals obtained from relativistic calculations.Translated from Teoreticheskaya i éksperimental'naya Khimiya, Vol. 24, No. 1, pp. 91–95, January–February, 1988.
