Abstract
Abstract The polarized reflectance spectra were measured on five [M(dmit)2] salts, i.e. Cs[Pd(dmit)2]2, Me4As[Pd(dmit)2]2, Me4N-[Ni(dmit)2]2, Me2Et2N[Ni(dmit)2]2, and EDT-TTF[Ni(dmit)2]. Plasma frequencies, and band parameters were estimated from the spectra by use of the Drude-Lorentz model. In the two palladium salts experimental evidences were presented for the anomalous “LUMO-HOMO energy level inversion” due to strong dimerization.
