Polarized far-infrared (FIR) spectroscopic measurements and FIR magneto-optical studies were performed on the inorganic spin-Peierls compound CuGeO3. An absorption line, which was found at 98 cm −1 in the dimerized phase (D phase), was assigned to a folded phonon mode of B3u symmetry. The splitting of the folded mode into two components in the incommensurate phase (IC phase) has been observed for the first time. A new broad absorption centered at 63 cm −1 was observed only in the E b axis polarization, which was assigned to a magnetic excitation from singlet ground state to a continuum state. 78.66.-w,78.30.-j,63.22.+m
