Task 188.8.131.52 Reactions of Organics With Ices and Mineral Grains
One focus is on understanding reactions occurring on Titan’s surface with an emphasis on determining whether mineral deposits from meteoritic infall can catalyze the formation of more complex molecules of prebiotic relevance such as amines, polyamines or simple amino acids.
Co-Investigator Thom Orlando and colleagues seek to develop a mapping technique using X-ray photoelectron spectroscopy to evaluate the influence of each mineral inclusion on the formation of P O-C bonds while thin ices are thermally processed.
First IR experiments were performed under purged N2 atmosphere at 77K and involved the reaction between an iron meteorite surrogate (Fe3P) and organics. These experiments suggest that Fe3P is non reactive toward some organics such as acetonitrile or formamide even under UV or green laser irradiations. The presence of the powder does not enhance nor accelerate the decomposition of these species under UV irradiations.
