The Case of H$_2$C$_3$O Isomers, Revisited: Solving the Mystery of the Missing Propadienone

, 2019
To date, two isomers of H$_2$C$_3$O have been detected, namely, propynal (HCCCHO) and cylclopropenone (c-H$_2$C$_3$O). A third, propadienone (CH$_2$CCO), has thus far eluded observers despite the fact that it is the lowest in energy of the three.

Metal-ion mediated photolytic regulation of diphenylalanine stability: Implications for prebiotic chemical evolution

iScience
Summary: Early Earth’s UV-rich environment, together with abundant transition metals, likely shaped the stability of biomolecules. We investigated how cations influence the UV (254 nm) stability of diphenylalanine (FF).

Electron-Induced Chemistry in the Condensed Phase

Atoms, 2019
Electron–molecule interactions have been studied for a long time. Most of these studies have in the past been limited to the gas phase. In the condensed-phase processes that have recently attracted attention from academia as well as industry, a ...

Infrared Spectroscopic and Physical Properties of Methanol Ices—Reconciling the Conflicting Published Band Strengths of an Important Interstellar Solid

The Astrophysical Journal
Infrared spectroscopic observations have established the presence of solid methanol (CH _3 OH) in the interstellar medium and in solar system ices, but the abundance of frozen CH _3 OH cannot be deduced without accurate band strengths, optical constants,

Division VI/Commission 34/Working Group Astrochemistry [PDF]

, 2011
The study of molecules in space, known as astrochemistry or molecular astrophysics, is a rapidly growing field. Molecules exist in a wide range of environments in both gaseous and solid form, from our own solar system to the distant early universe.

Superaromatics: The key to a unified cosmic dust theory [PDF]

The theory of Superaromatics, the key to a unified cosmic dust theory, was constructed by analyzing several thousand astronomical features covering every major aspect of astrophysics and astrochemistry relating to dust.
