Prebiotic synthesis initiated in formaldehyde by laser plasma simulating high-velocity impacts

Popis výsledku v původním jazyce

It is well known that hydrogen cyanide and formamide can universally be considered as key molecules in prebiotic synthesis. Several results indicate that formamide can play the role of important intermediate as well as that of a feedstock molecule in chemical abiogenesis. Here we report on a wide exploration of the formaldehyde reaction network under plasma conditions mimicking an asteroid descent in an Earth-like atmosphere and its impact. Dielectric breakdown using a high-power kJ-class laser system (PALS – Prague Asterix Laser System) have been employed in order to mimic an asteroid impact plasma. We show that plasma reprocessing of formaldehyde leads to the formation of several radical and molecular species along with formamide. Our results, supported by quantum mechanical and enhanced sampling simulations, show that formaldehyde may have had the role of starting substance in prebiotic synthesis.
