A combined experimental and theoretical study on the formation of intersteller C3H isomers

The reaction of ground-state carbon atoms with acetylene was studied under single-collision conditions in crossed beam experiments to investigate the chemical dynamics of forming cyclic and linear C3H isomers in interstellar environments via an atom-neutral reaction. The findings strongly correlate...

Description
Summary:The reaction of ground-state carbon atoms with acetylene was studied under single-collision conditions in crossed beam experiments to investigate the chemical dynamics of forming cyclic and linear C3H isomers in interstellar environments via an atom-neutral reaction. The findings strongly correlate with astronomical observations and explain a higher ratio in the dark cloud TMC-1 than in the carbon star IRCplus10216.
