The influence of the quadrupole interaction on the shape of ^{57}Fe Mössbauer spectra expected for samples with charge-density waves andor spindensity waves is investigated. It is shown, by model calculations, that both for the commensurate and for incommensurate charge-density waves andor spin-density waves the shape of ^{57}Fe Mössbauer spectra is sensitive to the value, and for asymmetric spectra, to the sign of quadrupole interaction. This necessitates an inclusion of quadrupole interaction when analyzing the spectra recorded on samples exhibiting charge-density waves andor spin-density waves, and having a symmetry lower than cubic.
