Emission lines from the Red Rectangle have been tentatively identified with DIBs, suggesting that the analysis of the emission bands might shed light on the nature and the identity of the DIBs carriers. Our new data, which have better spectral resolving power and S/N than previous observations, provide emission band profiles from various locations within the nebula, including the whiskers'' or bright arms of the cross-shaped pattern of the biconical nebula, and also selected locations within the nebula but between the whiskers. We will discuss the relationship between the DIBs and the emission bands in the Red Rectangle, in terms of both the general spectral distribution of DIBs as compared to the continuous emission (the so-called extended red emission, or ERE) and the specific matches of Red Rectangle emission bands and interstellar DIBs in absorption. We note a general coincidence between the ERE from the Red Rectangle and the overall distribution of DIBs with wavelength; and we critically evaluate earlier reports that some of the observed emission bands appear to coincide with known DIBs, with progressive wavelength shifts that may be attributed to varying rotational excitation in a moleculer carrier. We also examine the hypothesis that some of the DIB carriers are contributing to both the ERE and the emission bands in the Red Rectangle. en_US dc.format.extent 551655 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title THE APACHE POINT DIFFUSE BANDS SURVEY: EMISSION FROM THE RED RECTANGLE en_US dc.type article en_US
