Photodissociation of interstellar ArH+ [PDF]

open access: yesAstronomy & Astrophysics, 2014
Aims. Following the recent detection of 36ArH+ in the Crab nebula spectrum, we have computed the photodissociation rate of ArH+ in order to constrain the physical processes at work in this environment. Methods.

Photodissociation dynamics of N3+ [PDF]

open access: yesThe Journal of Chemical Physics, 2022
The photodissociation dynamics of N3+ excited from its (linear) 3Σg−/(bent) 3A″ ground to the first excited singlet and triplet states is investigated. Three-dimensional potential energy surfaces for the 1A′, 1A″, and 3A′ electronic states, correlating with the 1Δg and 3Πu states in linear geometry, for N3+ are constructed using high-level electronic ...

Wavelength-dependent photodissociation of iodomethylbutane

open access: yesScientific Reports
Ultrashort XUV pulses of the Free-Electron-LASer in Hamburg (FLASH) were used to investigate laser-induced fragmentation patterns of the prototypical chiral molecule 1-iodo-2-methyl-butane ( $$\hbox {C}_5$$ $$\hbox {H}_{11}$$ I) in a pump-probe scheme ...

The Catalyzed Photodissociation of Water [PDF]

open access: yesCatalysis Reviews, 1984
Abstract Chemical interactions between molecules in excited electronic, vibrational, or rotational states and surfaces is a new field of catalytic science. Until recently, catalysis of chemical reactions has only been considered for molecules in their thermodynamic ground states.

Breaking the Boring Billion

open access: yesGeophysical Monograph Series, Page 487-501., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Photochemical Micro-/Nano-Swelling of Silicone Rubber Induced by Long Pulse-Repetition Interval of an ArF Excimer Laser

open access: yesElectronic Materials, 2021
Long pulse-repetition intervals of 100 to 500 ms of a 193 nm ArF excimer laser successfully increased the height of the photochemical micro-/nano-swelling of silicone rubber, observed with a scanning electron microscope.

Three-isotope plot of fractionation in photolysis: A perturbation theoretical expression [PDF]

open access: yes, 2005
The slope of the three-isotope plot for the isotopomer fractionation by direct or nearly direct photodissociation is obtained using a perturbation theoretical analysis.

Iron monoxide photodissociation [PDF]

open access: yesThe Journal of Chemical Physics, 2005
The photodissociation of Fe56O was studied by means of the velocity map imaging technique. A molecular beam of iron atoms and iron monoxide molecules was created using an electrical discharge with an iron electrode in a supersonic expansion of molecular oxygen.

Nanoscale Vacancy-Mediated Aggregation, Dissociation, and Splitting of Nitrogen Centers in Natural Diamond Excited by Visible-Range Femtosecond Laser Pulses

open access: yesNanomaterials, 2023
Natural IaA+B diamonds were exposed in their bulk by multiple 0.3 ps, 515 nm laser pulses focused by a 0.25 NA micro-objective, producing in the prefocal region (depth of 20–50 μm) a bulk array of photoluminescent nanostructured microtracks at variable ...
