Photodissociation of interstellar ArH+ [PDF]

Astronomy & 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 OF PbCl2

Acta Physica Sinica, 1988
The population on 6p2 3P2 metastable state and 6p2 3P0 ground state of Pb atoms are de-monstrated, which are originated from dissociating PbCl2 by the fourth harmonic of YAG lasers. The population ratio of 3P2 to 3P0 is measured in terms of laser-induced fluorescence.

Wavelength-dependent photodissociation of iodomethylbutane. [PDF]

Sci Rep
Abstract 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. Ion velocity-map

Photodissociation dynamics of N3+ [PDF]

The 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 ...

Iron monoxide photodissociation [PDF]

The 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.

The Catalyzed Photodissociation of Water [PDF]

Catalysis 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.

Photodissociation of water in crystalline ice: a molecular dynamics study [PDF]

, 2005
Ultraviolet irradiation of ice is of great interest for understanding the chemistry in both atmospheric and astrophysical environments. In interstellar space, photodissociation of H2O molecules can be a driving force behind the chemistry on icy dust ...

C₆₀IN PHOTODISSOCIATION REGIONS [PDF]

The Astrophysical Journal, 2014
Recent studies have confirmed the presence of buckminsterfullerene (C$_{60}$) in different interstellar and circumstellar environments. However, several aspects regarding C$_{60}$ in space are not well understood yet, such as the formation and excitation processes, and the connection between C$_{60}$ and other carbonaceous compounds in the interstellar

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.

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}.
