| Abstract: | Kodak IM plates have been used in order to extend to 9600 Å the observed wavelength range for 23 O, B, Be Bp and A stars. The spectra are shown in the plate. Several atmospheric absorption bands perturb the continuum and line spectrum. Between 1.45 and 1.20
-1, we have measured the parameter d logI
 /d(1/). The results appear in the table and indicate that Be stars do not exhibit anomalous reddening in this spectral region. On the other hand the above parameter is much more sensitive to the reddening than to the star's effective temperature.Le matériel d'observation utilisé pour le présent travail a été obtenu à l'observatoire de Haute-Provence.
