Abstract
A new procedure for constructing double group symmetry functions is pr esented. Using this method integrals over Hermitian operators can beco me real quantities, even though the integrand and the functions themse lves are complex. This is especially of interest to 4-component relati vistic methods that use the Dirac-Coulomb Hamiltonian directly in elec tronic structure calculations.
