The nature of the boson peak in the low-wavenumber Raman spectra of (Na 2 O) x -(B 2 O 3 ) 1-x glasses is analyzed to be a manifestation of intermolecular interactions within regions of inhomogeneity, which are inherent to all glasses. The wavenumber of the boson peak satisfies the modified Szigeti
