Abstract
The infrared conductivities of four organic conductors with partially filled one-electron bands are compared. The behavior ranges from near Drude type in the best metal to semiconductorlike in the moderate conductor. Electron-molecular-vibration coupling effects of varying degree are seen in all materials. It is suggested that the combined effect of electron-electron interaction and electron-phonon interaction in producing charge-density waves is essential for interpreting the results.
