AlF–AlF Reaction Dynamics between 200 K and 1000 K: Reaction Mechanisms and Intermediate Complex Characterization

open access: yesMolecules, 2023
AlF is a relevant molecule in astrochemistry as a tracer of F-bearing molecules. Additionally, AlF presents diagonal Franck-Condon factors and can be created very efficiently in the lab, which makes it a prototypical molecular for laser cooling. However,

Infrared Spectra and Vapor Pressures of Crystalline C2N2, with Comparisons to Crystalline HCN

open access: yesThe Planetary Science Journal, 2023
In a continuation of our work on nitriles, we have examined cyanogen (C _2 N _2 ) as a crystalline solid, comparing the results to our recent work on crystalline hydrogen cyanide (HCN).

Influences on Infrared Spectra of Benzene Ices for Titan, Comets, and Beyond: Annealings, Artifacts, and Isosbestic Points

open access: yesThe Planetary Science Journal, 2023
Infrared (IR) spectra are needed for both laboratory and observational studies of extraterrestrial ices, both within the solar system, such as for trans-Neptunian objects, comets, and Titan, and in the interstellar medium.

Gas-phase Ortho-to-para Ratio of Formaldehyde Formed at Low Temperatures in Laboratory Ices

open access: yesThe Astrophysical Journal Letters, 2023
The ortho-to-para ratio (OPR) of formaldehyde (H _2 CO) has been used as a probe to estimate the formation temperature of molecules in interstellar, circumstellar, and cometary environments, relying on the assumption that nuclear spin conversion is ...

Exploring outer space biophysical phenomena via SpaceLID

open access: yesScientific Reports, 2023
Extensive investigations in outer space have revealed not only how life adapts to the space environment, but also that interesting biophysical phenomena occur. These phenomena affect human health and other life forms (animals, plants, bacteria, and fungi)

Anatomy of Orion Molecular Clouds—The Astrochemistry Perspective/Approach

open access: yesFrontiers in Astronomy and Space Sciences, 2021
The Orion molecular cloud (OMC) complex is the nearest and perhaps the best-studied giant molecular cloud complex within which low-mass and massive star formation occur. A variety of molecular species, from diatomic molecules to complex organic molecules
