VUV Spectra of Ice Isoprene Reveal ISM Signatures at 10 K
New findings on the VUV spectra of icy isoprene and terpenes Isoprene and its related terpenes are key organic molecules in many astrochemical environments. From the vastness of the interstellar medium (ISM) to the icy surfaces of solar system bodies, these compounds are expected to exist but have remained only partially characterized. A recent study…

Vacuum Ultraviolet Photoabsorption Spectra of Isoprene Ices and Terpenes at 10 K
Overview and significance Isoprene and its oligomers, including limonene, α-pinene and β-pinene, are volatile organics of interest in interstellar chemistry and planetary environments. However, spectral fingerprints for these molecules when frozen as icy mantles on dust grains — conditions common in dense interstellar clouds and outer solar system bodies — have been insufficiently characterized at…
