heal.abstract	We present the room temperature far-infrared reflectivity and Raman scattering spectra of NaV2O5 single crystals. The frequencies of infrared active modes are obtained by an oscillator fitting procedure of reflectivity data. The assignment of the vibrational modes is given according to a lattice dynamical calculation based on the valence shell model. Besides phonon modes we observed broad features centered at about 280, 550 and 3500 cm(-1) in infrared spectra for E parallel to a polarization and at about 640 cm(-1) in Raman spectra for (aa) polarization. These structures are explained as crystal-field-splitting-induced d-d electronic transitions of V4+ ions. (C) 1999 Elsevier Science Ltd. All rights reserved.	en
