The optical absorption of α‐rhombohedral boron was investigated in the spectral range of the absorption edge, and in the MIR and FIR spectral range especially with respect to the lattice vibrations. The phonon spectrum was investigated by Raman scattering, too. The decomposition of the absorption edge yields three different transitions. The phonon spectra are discussed with respect to theoretical calculations. The isotope effect is considered.
