We present an accurate first-principles study of the electronic structure and absorption spectrum of six elemental metals (aluminium, gold, silver, copper, palladium, platinum) using density functional theory in an all-electron full-potential framework. We calculate dielectric function spectra and plasma frequency, and compare with experimental data obtained from photo-emission, absorption, and electron energy loss spectra.
