抄録

The magnetic circular dichroism (MCD) spectra of K2PtCl4 and K2PdCl4 have been carefully remeasured over the visible-near UV region. The examination of the electronic absorption and the MCD spectra together with their Gaussian analyses strongly suggests that the band of K2PtCl4 at 30.3×103 cm−1 contains both Γ5(1Eg) and Γ3(1B1g)←Γ1(1A1g) transitions, and the band of K2PdCl4 at 21.1×103 cm−1 all three spin-allowed d-d transitions. The separation of the Γ2(1A2g) and Γ5(1Eg) excited states is considerably large with K2PtCl4 as compared with K2PdCl4. The MCD for the high-intensity absorption bands in K2PtCl4 is different from that reported previously. On the basis of new MCD result, the bands at 43.3 and 46.6×103 cm−1 have been assigned to d-p transitions, a2u(pz)←a1g(dz2) and eg(dxz,yz), respectively.
