Solid-phase formation of interstellar vinyl alcohol.

HUDSON R.L. and MOORE M.H.

Abstract (from CDS):

Motivated by the recent discovery of gas-phase interstellar vinyl alcohol, CH2CH(OH), we present laboratory experiments on this molecule's solid-phase formation. Through a combination of reaction chemistry, infrared spectroscopy, isotopic substitution, thermal annealings, and independent syntheses, we have identified vinyl alcohol in proton-irradiated H2O+C2H2ices and have measured its column density at ∼15 K. UV photolysis of H2O+C2H2 ices at ∼15 K also produces vinyl alcohol. It is suggested that vinyl alcohol is formed in interstellar ices and then ejected into the gas phase, where it might undergo additional reactions.
