Surface Formation Routes of Interstellar Molecules A Laboratory Study

1. Hydrogenation of CO ice provides an efficient pathway to form both interstellar solid H2CO and CH3OH at low temperatures.

Chapters 2 and 7

2. The water formation reaction network described by Tielens & Hagen (1982) is more complex than proposed.

Chapters 3 - 6

3. The surface formation of CO2 is chemically linked to the formation of H2O in the ice.

Chapter 7

4. CO2 can be formed in the solid phase with and without energetic input.

Chapters 7 and 9

5. Surface reactions in simple ices may reveal a complex solid state chemistry.

6. A bottom-up and a top-down approach have one thing in common: the middle.

7. The past decades have proven the importance of a good interaction between astronomical observations, laboratory experiments and astrochemical modeling.

8. The research of knowledge brings wealth.

9. Finishing a PhD is like climbing a long mountain route: the sky is the limit and falling down is not an option.

10. H-atom bombardment as an email subject header may attract the attention of non-scientists.

11. Extreme climatic conditions are the worst enemies of cyclists.

12. My best proposition is the one I have not written yet.

The two isomers of methyl isocyanate - acetonitrile oxide (CH 3 CNO) and methyl cyanate (CH 3 OCN) - are not found and are less abundant than methyl isocyanate by at least two and

If HNCHO is formed in a similar radical ad- dition reaction as NH 2 CO (i.e. NH + CHO), reduction or hydrogenation reactions can result in HNCO and NH 2 CHO formation. Since

We have performed a quantitative study of the CO 2 formed in laboratory C- and O- bearing samples upon energetic processing, and we extended our results to the interstellar medium

In this thesis a number of these questions will be addressed, focusing on low temperature solid state chemistry, ice evaporation, and gas phase species after ice evaporation (see

presented spectroscopic laboratory gas phase data for the fullerene cation, C 60 + , that coincide with the reported astronomical spectra of two diffuse interstellar band (DIB)

The studies are motivated by the potential for spectroscopic astronomical detection of electronic absorption spectra of PAHs in ice mantles on interstellar grains as discussed

Furthermore, there is a need to transform the results of laboratory studies of surface processes (sticking, di ffusion, desorption, energy partition, etc.) to the e fficiency
