The infrared reflection spectra of the organic quasi-one-dimensional semiconductor triethylammonium (TCNQ)_{2} between 80 and 300 K are reported. Characteristic changes in the temperature dependencies of the bands assigned to the donor vibrations are observed. An interpretation of the electron-molecular vibration coupling in terms of the dimer theory is discussed. It is concluded that the thermal evolution of the spectrum corroborates the semiconductor-semiconductor type of phase transition attributed to the cation disorder.
