  "abstract": "The “unidentified infrared (IR) emission” (UIE) bands at 3.3, 6.2, 7.7, 8.6, 11.3, and 12.7 μ m are ubiquitously seen in a wide variety of astrophysical environments. While the exact assignment of these UIE bands remains controversial, they are generally ascribed to C–H and C–C stretching and bending vibrations of aromatic hydrocarbon molecules. Here, based on observations made with the Near-Infrared Spectrograph (NIRSpec) and the Mid-Infrared Instrument (MIRI) on board the James Webb Space Telescope (JWST), we report that the UIE emitters in the 30 Doradus star-forming complex in the Large Magellanic Cloud (LMC) are deuterated and have an appreciable amount of aliphatic content. The spatially resolved NIRSpec and MIRI spectra of 30 Doradus reveal a widespread detection of the 3.4 and 6.85 μ m emission features attributed to aliphatic C–H stretch and deformation, respectively, as well as the 4.65 μ m feature attributed to aliphatic C–D stretch. Notably, the 6.85 μ m feature exhibits three complex substructures at ∼6.83, 6.86, and 6.88 μ m that have never been reported before.",
