Context. Vacuum-ultraviolet (VUV) photons are important drivers of chemical processes in
space. Thus, it is important to accurately characterize and constrain photorates in different …

Organic acids play a key role in the troposphere, contributing to atmospheric aqueous-
phase chemistry, aerosol formation, and precipitation acidity. Atmospheric models currently …

We report here a full-dimensional machine learning global potential surface (PES) for the
rearrangement of methylhydroxycarbene (H3C–C–OH, 1t). The PES is trained with the …

We have analyzed near-global stratospheric data (and mesospheric data as well for H 2 O)
in terms of absolute abundances, variability, and trends for O 3, H 2 O, HCl, N 2 O, and HNO …

Acetaldehyde is one of the key small organic molecules involved in astrochemical and
atmospheric processes occurring under the action of ionizing and UV radiation. While the …

The photolysis of acetylacetone (AcAc) has been studied using velocity-map ion imaging
with pulsed nanosecond lasers. The enolone tautomer of AcAc (CH3C (O) CH═ C (OH) …

Chemical reactions are often characterized by their transition state, which defines the critical
geometry the molecule must pass through to move from reactants to products. Roaming …

The photodissociation dynamics of jet-cooled trifluoroacetaldehyde (CF 3 CHO) into radical
products, CF 3+ HCO, was explored using velocity mapped ion imaging over the wavelength …

The roaming mechanism, an unconventional reaction path, was discovered more than a
decade ago in the studies of formaldehyde photodissociation, H2CO→ H2+ CO. Since then …

The first experimental observation of the primary photochemical channel of acetaldehyde
leading to the formation of ketene (CH2CO) and hydrogen (H2) molecular products is …
