Amorphous 1-Propanol in Interstellar Ices – Crystallization Revisited

Year: 2024

Type: article

Abstract: A recent publication described laboratory measurements of infrared spectra of solid 1-propanol, a likely interstellar ice component. The authors concluded that amorphous 1-propanol does not produce crystalline 1-propanol on warming and that 1-propanol remains as a solid far above its melting point. New laboratory results presented here show that both conclusions are false. A spectrum of crystalline 1-propanol is presented along with the first band strengths for two infrared features in both the amorphous and crystalline forms of the compound. Extensions and astrochemical applications are described.
