diffuse interstellar bands

(DIBs)
(type of absorption bands seen in astronomical objects)

Diffuse interstellar bands (DIBs) are absorption bands seen in astronomical objects that are clearly due to some kind of ISM absorption. They are now attributed to polycyclic aromatic hydrocarbons and similar carbon molecules and buckminsterfullerene (C60) has been identified in some.
