The far-infrared properties of (TMTSF)/sub 2/ ClO/sub 4/ have been measured for frequencies between 4 and 40 cm/sup -1/. At 2K, phonon-like peaks in reflectance are seen at 7 and 29 cm/sup -1/. Increasing the temperature to 80K causes these peaks to gradually disappear, but not to shift appreciably in frequency. Radiation-induced defects substantially reduce the height of the 29 cm/sup -1/ peak with a magnetic field of up to 40 KG applied parallel to the C*-axis. These results suggest a coupled electronic-molecular vibration origin for these features. They are incompatible with the recently proposed /1/ interpretation of the 29 cm/sup -1/ feature as a quasi-one-dimensional superconductive pseudogap.
