Reflectance spectra of 2:1 charge‐transfer salt single crystals of deuterated bis(ethylenedithio)tetrathiafulvalene (BEDT‐TTF) cation with Hg(SCN) 2 Br are reported for two polarizations and compared with the data for the hydrogenated compound. The Hubbard‐type model for two orthogonal dimers in the case of infinite on‐site Coulomb repulsion U is developed and emlpoyed for the interpretation of the observed charge‐transfer bands and vibrational peaks resulting from electron–molecular vibration coupling.
