摘要：

The reflectance spectra of (BEDT-TTF)5Hg3Br11 and (BEDT-TTF)HgBr3 were measured by using the microspectrophotometric technique in the spectral range from 450 cm-1 to 25000 cm-1. In the former salt, the gap formation due to a metal-insulator transition was observed in the reflectance spectrum at 100 K. In the latter salt, the effective Coulomb interaction and the intra-dimer transfer integral were estimated and compared with the corresponding values of BMDT-TTF and TTF.
