The reflectance spectra of (BEDT-TTF)<SUB>5</SUB>Hg<SUB>3</SUB>Br<SUB>11</SUB> and (BEDT-TTF)HgBr<SUB>3</SUB> were measured by using the microspectrophotometric technique in the spectral range from 450 cm<SUP>−1</SUP> to 25000 cm<SUP>−1</SUP>. 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.
