【 摘 要 】

Raman and infrared spectra of several organic superconductors are presented, showing some unusual behaviors of a sharp line at 890 cm(sup (minus)) in both spectra. These include a frequency shift below T(sub 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 v(sub 60)(B(sub 3g)) mode component.
