Abstract

Observations of IRAS 21282 + 5050 and IRAS 03055 + 5819 (AFGL 437) obtained at 7.7-22.5 microns using the IRAS LRS during 1983 and at 3.1-3.8 microns using the 3.75-m UKIRT in September 1985, are reported and analyzed. The data are presented graphically, and the significance of three new nonatomic emission features at 3.46, 3.51, and 3.56 microns; the known emission features at 3.3, 3.40, 7.7, 8.6, and 11.3 microns; and the plateaus at 3.4-3.6 and above 11.5 microns is discussed in detail. It is suggested that the plateau and narrow features between 3.4 and 3.6 microns may be due to polycyclic aromatic hydrocarbons with attached molecular subgroups such as -CH3 or -C2H5, a hypothesis developed by analogy to that proposed by Cohen et al. (1985), and Puget et al. (1985) for the 12-micron plateaus seen in many IRAS spectra.
