We compare the relativistic LDA Fermi surface of Sr(2)RuO(4) to direct experimental evidence of spin-orbit coupling from de Haas-van Alphen experiments. The k-dependence of the Zeeman splitting at the Fermi surface is modelled with a range of tight binding models of the quasi-particle bands. Only a very restricted class of parameters are consistent with evidence from the de Haas-van Alphen experiments for a strong k-dependent Zeeman splitting on the alpha Fermi surface sheet. The bare LDA bands do not lead to such a strong k-dependent Zeeman splitting on this sheet, and this suggests that additional charge transfer takes place as suggested by DMFT calculations. We conclude that the overall scale of the spin-orbit coupling must be at least as large as the several hundred kelvin deduced in previous work, and that this must call into question any theory postulating rotation of the triplet d-vector at small magnetic fields.
