Scientific paper

Detailed optical spectrophotometry of seven WR stars based on medium dispersion spectra are presented. Equivalent widths and FWHM of almost all lines in the optical region are measured, absolute continua are determined, dereddened line fluxes are presented, the ionization potential versus 1/2 FWHM graphs are constructed, and new tentative identifications of S VI lines are proposed.
