We have measured the polarized reflectivity spectra of three BETS-based organic metals with the a-phase structure: a-(BETS)2NH4Hg(SCN)4 (I), a-(BETS)2TlHg(SeCN)4 (II), and a-(BETS)2Cu5I6 (III) in the range of 600-6500 cm-1. The spectra exhibit a metallic-type reflection with the plasma edge about 4000-5000 cm-1 and high reflectivity at low frequencies. The electron-vibrational bands observed in the range of 1200-1400 cm-1 are due to the interaction of the intramolecular vibrational modes of BETS with conduction electrons.
