Popis: Raman and infrared spectra of several organic superconductors are presented, showing some unusual behaviours of a sharp line at 890 cm −1 in both spectra. These include a frequency shift below T c , a positive deuterium isotope shift, frequency softening at low temperatures and sensitivity to lattice superstructure. It is proposed that either the ion or the neutral molecule has a distortion with a strong ν 60 (B 3g ) mode component.
