The collection of 21 stellar spectra was obtained in December 1990 by the authors using the Aurelie Spectrograph of Haute Prpvence Observatory (HPO). The wavelength range is 7500-8800 Angstrom. Binary stars which are observed for this spectral atlas is selected from Hegedüs (1988) list of eclipsing binaries showing apsidal motion. This list contains binary systems with well-confirmed apsidal motion (OX Cas, PV Cas, AG Per), systems with undoubted but weakly proved, or questionable apsidal motion (AO Cas, CC Cas, V373 Cas, V1765 Cyg, RR Lyn, IQ Per, o Per), systems with eccentric orbit or displaced secondary minimum (AN And, WW Aur, AR Aur, EO Aur, RZ Cas, V1488 Cyg, IZ Per, V436 Per, EPS UMi, HD 208947, HD 218407).
