Energy level diagram of the C + NH3 + CO reaction. The reaction proceeds from left to right. It starts with a triplet state; the intersystem crossings to the singlet states are marked with dashed arrows. S and TS stand for singlet and transition states. Red lines indicate the most probably pathway. -- astro-ph.GA

Chemical Modeling Of Aminoketene, Ethanolamine, And Glycine Production In Interstellar Ices

by Keith CowingOctober 28, 2025October 28, 2025

Icy interstellar dust grains are a source of complex organic molecule (COM) production, although their formation mechanisms are debated.

This artist’s impression shows the planet-forming disc around the star V883 Orionis. In the outermost part of the disc, volatile gases are frozen out as ice, which contains complex organic molecules. An outburst of energy from the star heats the inner disc to a temperature that evaporates the ice and releases the complex molecules, enabling astronomers to detect it. The inset image shows the chemical structure of complex organic molecules detected and presumed in the protoplanetary disc (from left to right): propionitrile (ethyl cyanide), glycolonitrile, alanine, glycine, ethylene glycol, and acetonitrile (methyl cyanide).

Ly-α Processing of Solid-state Ethanolamine: Potential Precursors to Sugar and Peptide Derivatives

by Keith CowingFebruary 13, 2025February 13, 2025

Ethanolamine (EA), a key component of phospholipids, has recently been detected in the interstellar medium within molecular clouds.

Evidence for the formation of two-center one-electron (2c–1e) bonds in the predissociation complexes of the radical cations in ethanolamine (A), propanol (B), butanenitrile (C), and glycolamide (D). The ELF basins are shown in the left column, the projections into the heavy atom planes are shown in the second column, the spin densities for the unpaired electrons are shown in the third column, and the 2c–1e AdNDP orbitals are shown in the right column. -- Chemical Science

What Drives The Formation Of Unsaturated Molecules In The Interstellar Medium?

by Keith CowingJanuary 20, 2025January 19, 2025

We present a computational investigation into the fragmentation pathways of ethanolamine (C2H7NO, EtA), propanol (C3H8O, PrO), butanenitrile (C4H7N, BuN), and glycolamide (C2H5NO2, GlA)—saturated organic molecules detected in the interstellar medium […]
