Key Points

This research aims to investigate the photochemical behavior of diacetylene ices and its implications for molecular complexity in Titan's atmosphere.
Analyzed diacetylene ices under vacuum ultraviolet light to study photochemical reactions.
Examined the resulting molecular changes and products formed during the photochemical process.
Diacetylene ices exhibit distinct photochemical properties depending on the phase, leading to varying product formations.
Findings suggest that the complexity of organic molecules increases in Titan's atmosphere due to these photochemical processes.

Implication

Explores photochemical processing in diacetylene ices, indicating implications for Titan's atmosphere.

Abstract

The photochemical processing of organic ices is a key driver of molecular complexity in planetary atmospheres and surfaces. On Titan, diacetylene (C4H2) has been detected in the atmosphere and is...
