Topics:

  1. Astronomical surveys: overall properties and statistics of the Diffuse Interstellar Bands (DIBs) and their relation to known interstellar species and components (C, Si, atomic and molecular hydrogen, C2, dust, ...).
  2. DIB behaviour in different (and extreme) environments.
  3. What can we learn from analyzing DIB line profiles and correlations?
  4. DIBs and the connection to other astronomical phenomena (Extended Red Emission, Unidentified InfraRed bands, UV extinction,...)
  5. Laboratory Astrophysics: current status and limitations of spectroscopy of potential DIB carriers.
  6. Laboratory Astrophysics: what carriers can thrive & survive in DIB environments: stability & irradiation studies, hydrogenation, ...
  7. General properties of the most commonly suggested classes of DIB carriers: carbon chains, polycyclic aromatic hydrocarbon (PAH) molecules, fullerene compounds.
  8. Theoretical and computational approaches & needs: quantum chemistry calculations (DFT, ...), chemical network models, astrophysical models.
  9. How can recent and future observatories & instruments (HST/COS, SOFIA, ALMA, JWST, VLT, ELTs,...) contribute to help narrowing or eventually solving the DIB problem?
  10. What are the most promising avenues toward identifying the DIB carriers?
