A new collection of photodissociation and photoionisation cross sections for 102 atoms and
molecules of astrochemical interest has been assembled, along with a brief review of the …

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 …

Current atmospheric models underestimate the production of organic acids in the
troposphere. We report a detailed kinetic model of the photochemistry of acetaldehyde …

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

The correlated speed and rotational energy distributions of the CO fragment from
photodissociation of CH3CHO have been measured at a range of wavelengths from 308 to …

An alternative to the transition state (TS) pathway, the roaming route, which bypasses the
minimum energy path but produces the same molecular products, was recently found in …

Measuring the isotopic abundance of hydrogen versus deuterium atoms is a key method for
interrogating reaction pathways in chemistry. H/D 'scrambling'is the intramolecular …

We investigate the gas-phase photochemistry of the enolone tautomer of acetylacetone
(pentane-2, 4-dione) following S2 (ππ*)← S0 excitation at λ= 266 and 248 nm, using three …

Radical quantum yields have been measured following the 248 nm photolysis of
acetaldehyde, CH 3 CHO. HCO radical and H atom yields have been quantified by time …

We present a quasiclassical trajectory study of the photodissociation of CH3CHO using a
global ab initio-based potential energy surface. Calculations are performed at a total energy …
