The emission band at 5.25 mu m and its relationship to the unidentified emission features at 11-13 and 3.4-3.6 mu m
Spectra at 5-5.6 μm are presented of three planetary nebulae with strong unidentified infrared (UIR) emission bands. All three objects display the 5.25-μm emission band which is attributed to a combination band arising from out-of-plane C-H bending modes. The profiles of the 5.25-μm bands are closel...
