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 […]

Column density of the various molecules from the ALMA Band 7 observations (PILS; ∼345 GHz) as a function of those from Band 3 (∼100 GHz). Beam dilution is corrected for the column densities in this figure. Dashed lines present where the values of y-axis are the same as values of x-axis, where they are 10 times higher and 10 times lower than the values of x-axis. -- astro-ph.GA

A Deep Search For Large Complex Organic Species Toward IRAS16293-2422 B At 3 mm With ALMA

by Keith CowingJanuary 12, 2024January 12, 2024

Complex organic molecules (COMs) have been detected ubiquitously in protostellar systems. However, at shorter wavelengths (~0.8mm) it is more difficult to detect larger molecules than at longer wavelengths (~3mm) because […]
