Photoinduced infrared absorption of quasi-one-dimensional halogen-bridged binuclear transition-metal complexes

Abstract
We investigate the optical conductivity of photogenerated solitons in quasi-one-dimensional halogen-bridged binuclear transition-metal MMX complexes with particular emphasis on a comparison among the three distinct groups: A4[Pt2(P2O5H2)4X]nH2O (X=Cl,Br,I; A=Na,K,NH4,...), Pt2(RCS2)4I (R=CnH2n+1) and Ni2(CH3CS2)4I, which exhibit a mixed-valent ground state with the X sublattice dimerized, that with the M2 sublattice dimerized and a Mott-Hubbard magnetic ground state, respectively. Soliton-induced absorption spectra for A4[Pt2(P2O5H2)4X]nH2O should split into two bands, while that for Pt2(RCS2)4I and Ni2(CH3CS2)4I should consist of a single band. The excitonic effect is significant in Ni2(CH3CS2)4I.
