Content

The origin of diffuse interstellar bands (DIBs)$^1$ and the unidentified infrared emission bands (UIEs)$^2$ are long standing questions of modern astrophysics. DIBs are absorption features of astronomical objects in the visible to near-infrared range whereas the UIEs can be found in the emission spectra of astronomical objects. At the Max Institute for Nuclear Physics we are developing a new spectroscopy technique for gas phase molecular ions that combines a cryogenic ion trap with extremely sensitive mid-infrared detectors. The measurement scheme, preparatory work toward its implementation, and the current status of the experimental setup will be presented.
