Interstellar nanodiamonds: the carriers of mid-infrared emission bands?

In this paper we pursue the natural consequences of the structure of nanodiamonds and their surface relaxation and reconstruction to surfaces exhibiting sp2 carbon atoms. We show that in the interstellar radiation field nanodiamonds can be stochastically heated to temperatures as high as 1000 K and give rise to discrete emission bands associated with the surface structures. We therefore speculate that nanodiamonds can make a significant contribution towards the m unidentified mid-infrared emission bands.
