Abstract New lines are observed in the infrared spectrum of a crystal due to unit-cell doubling at a spin-Peierls transition (in NaV2O5). The change in the shape of the spectral lines at the spin-Peierls transition is recorded. A contour characteristic of a Fano resonance is observed above the transition temperature T sp and the standard symmetric contour is observed below T sp . We attribute this effect to the opening of a gap in the magnetic-excitation spectrum at the spin-Peierls transition.
