[HTML][HTML] Identification of the'unidentified'IR emission features of interstellar dust?
A Leger, JL Puget�- …�and Astrophysics (ISSN 0004-6361), vol�…, 1984 - adsabs.harvard.edu
A consistent explanation for the so-called unidentified IR emission features of interstellar
dust is proposed. Following Sellgren (1984), the transient heating of very small grains to a
peak temperature of about 1000 K by the absorption of a single UV photon is considered,
and the subsequent IR emission is estimated. It is shown that graphite is one of the few
solids that would not sublime under such conditions, and that the stretching modes of the CH
radicals resulting from the conditions give an excellent fit to the observed 3.28 micron�…
