Interstellar ice: the infrared space observatory legacy.

Abstract (from CDS):
Features that continue to defy identification include the 3.3-3.7 µm ``ice band wing'' and the bulk of the 6.8 µm feature. In addition, we find evidence for excess absorption at 6.0 µm that cannot be attributed to H2O ice. We examine the degree of intercorrelation of the 6.8 µm, 4.62 µm (``XCN'') and 6.0 µm (excess) features. Our results are consistent with the interpretation of the 6.8 and 4.62 µm features as due to NH+4and OCN– ions, respectively, though alternative explanations cannot currently be ruled out. We find that the optical depth correlations are dependent on the profile of the 6.8 µm feature but not on the mass of the YSO nor the ice temperature along the line of sight. We discuss the implications for our current understanding of ice processing. We briefly discuss the composition, origin, and evolution of interstellar ices.
