Abstract
A Raman-scattering study performed on beta-BaB2O4 (beta-BBO) at room t emperature allows us to assign all the vibrational modes detected in t he Raman spectra. The internal and external vibration modes are proper ly obtained by taking account of the light polarization, mode contamin ation and isotope effects. A correspondence between the lattice and th e free-ring modes is also presented.
