Abstract
The infrared absorption spectrum of hydrogenated amorphous carbon solids shows features at 3.38, 3.41 and 3.48 μm corresponding to discrete bands in the spectrum of IRS-7. Interstellar amorphous carbon dust with chemisorbed CH2 and CH3 groups may be a significant component of interstellar dust in diffuse clouds.Keywords
