Absorption bands identified with DIBs

From comparison of observed and synthetic spectra of IRAS04296 we revealed some strong absorptional features whose positions coincide with known diffuse interstellar bands (DIBs) (Jenniskens et al., 1994). In Fig.5 we illustrate the presence of DIB's by showing a spectral region of IRAS04296. We have calculated the synthetic spectrum using the code STARSP (Tsymbal 1995) and the atmospheric parameters and abundances of chemical elements we here obtained. It should be noted that for such a comparison in the spectral range near ${\rm \lambda}$ 6270-6310Å the telluric spectrum has been removed from the observed spectrum.

In the following paper we plan to study in detail such identified with DIB's absorptions, we have revealed in the spectra of several related objects (IRAS04296, IRAS23304+6147, IRAS222223+4327), here we limited ourself by such short information.
