Experiments identify acenaphthene derivatives from C11H9+ reactivity with methylated naphthalenes and link them to efficient formation of acenaphthylene-like species in cold clouds.

abstract
We present an extensive review of gas phase reactions producing methylacetylene and propene showing that these relatively abundant unsaturated hydrocarbons cannot be synthesized through gas-phase reactions. We explain the formation of propene and methylacetylene through surface hydrogenation of C3 depleted onto interstellar ices, C3 being a very abundant species in the gas phase.

Acenaphthene Derivatives as Signatures of C$_{11}$H$_9^+$ Reactivity with Methylated Naphthalenes
Experiments identify acenaphthene derivatives from C11H9+ reactivity with methylated naphthalenes and link them to efficient formation of acenaphthylene-like species in cold clouds.
