Photodissociation and photoionisation of atoms and molecules of astrophysical interest [PDF]
, 2017 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 basic processes involved.

Photodissociation Regions [PDF]
Faraday discussions, 2011 The interstellar medium is known to be chemically complex. Organic molecules with up to 11 atoms have been detected in the interstellar medium, and are believed to be formed on the ices around dust grains.

Structure of Stationary Photodissociation Fronts [PDF]
, 1996 The structure of stationary photodissociation fronts is revisited. H_2 self- shielding is discussed, including the effects of line overlap. We find that line overlap is important for N(H_2) > 10^{20} cm^{-2}.

Photodissociation and X-Ray-Dominated Regions [PDF]
Annual Review of Astronomy and Astrophysics, 2022 The radiation from stars and active galactic nuclei (AGNs) creates photodissociation regions (PDRs) and X-ray-dominated regions (XDRs), where the chemistry or heating are dominated by far-ultraviolet (FUV) radiation or X-ray radiation, respectively. PDRs

Photodissociation of particulate nitrate as a source of daytime tropospheric Cl2
Nature Communications, 2022 Chlorine atoms (Cl) are highly reactive and can strongly influence the abundances of climate and air quality-relevant trace gases. Despite extensive research on molecular chlorine (Cl2), a Cl precursor, in the polar atmosphere, its sources in other ...

Molecular photodissociation enabled by ultrafast plasmon decay. [PDF]
Journal of Chemical Physics, 2020 We propose a strategy for enabling photodissociation of a normally photostable molecule through coupling to a nanoparticle plasmon. The large possible coupling on the single-molecule level combined with the highly lossy nature of plasmonic modes, with ...

A method for calculating temperature-dependent photodissociation cross sections and rates
Physical Chemistry, Chemical Physics - PCCP, 2021 The destruction of molecules by photodissociation plays a major role in many radiation-rich environments, including the evolution of the atmospheres of exoplanets, which often exist close to UV-rich stars.

Nature Communications, 2022 The photodissociation of transition metal carbonyls is involved in catalysis and synthetic processes. Here the authors, using semi-classical excited state molecular dynamics, observe details of the early stage dynamics in the photodissociation of Fe(CO)5,

Frontiers in Chemistry, 2020 We present a contemporary mechanistic description of the light-driven conversion of cyclopropenone containing enediyne (CPE) precusors to ring-opened species amenable to further Bergman cyclization and formation of stable biradical species that have been
