The radiative association of PO/PH+ and the photodissociation of PH+

Frontiers in Astronomy and Space Sciences
The potential energy curves (PECs) and transition dipole moments (TDMs) of PH+ and PO are computed with the multireference configuration interaction method, and the cross-sections for the radiative association (RA) of PH+ and PO, which is the most ...

Indistinguishability and Interference in the Coherent Control of Atomic and Molecular Processes

, 2010
The subtle and fundamental issue of indistinguishability and interference between independent pathways to the same target state is examined in the context of coherent control of atomic and molecular processes, with emphasis placed on possible "which-way"

Control of the Jovian Magnetopause by Iogenic Plasma: Initial Results From Global MHD Simulations

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract The size and variability of Jupiter's magnetosphere are not only determined by upstream conditions but also substantially influenced by internal processes within Jupiter's magnetosphere, specifically the dynamics of the rotation magnetodisc.

Grain Dynamics in Photodissociation Regions [PDF]

arXiv, 1998
We discuss the forces on grains exposed to anisotropic radiation fields, including the usual ``radiation pressure'' force and also recoil forces due to photoemitted electrons, photodesorbed hydrogen atoms, and hydrogen molecules which form on the grain surface.

Theoretical Models of Photodissociation Fronts [PDF]

arXiv, 2000
Observations of H2 line emission have revealed higher-than-expected gas temperatures in a number of photodissociation fronts. We discuss the heating and cooling processes in photodissociation regions. Observations of NGC 2023 are compared to a theoretical model in which there is substantial gas at temperatures T = 500-1000K heated by photoelectric ...

Mechanistic Investigation of an Organocatalytic Bromocyclization of O‐Allyl Carbamates

ChemCatChem, Volume 17, Issue 8, April 15, 2025.
The enantioselective bromoaminocyclization of O‐cinnamyl tosylcarbamates catalyzed by thiourea‐functionalized Cinchona alkaloids achieved 80:20 er and 69% isolated yield. Experimental and theoretical studies reveal key bromonium intermediates and non‐covalent interactions stabilizing the catalytic structure. This model reaction elucidates the mechanism

Hydroxyl super rotors from vacuum ultraviolet photodissociation of water

Nature Communications, 2019
Free electron lasers provide a state-of-the-art tool to investigate the photochemistry of water. Here, the authors show that highly rotationally excited hydroxyl radicals, so-called “super rotors” existing above the bond dissociation energy, are observed

Dissociation Dynamics of CIONO_2 and Relative Cl and ClO Product Yields following Photoexcitation at 308 nm [PDF]

, 1995
Chlorine nitrate photolysis at 308 nm has been investigated with a molecular beam technique. Two primary decomposition pathways, leading to Cl + NO_3 and ClO + NO_2, were observed.

Integrating Flow Chemistry With Electrospray Ionization Mass Spectrometry

Chemistry–Methods, Volume 5, Issue 4, April 2025.
The direct integration of flow chemistry with electrospray ionization‐mass spectrometry is emerging as a method for real‐time monitoring of reaction mixtures under well‐defined conditions. As shown in selected examples, this interface facilitates the characterization of reaction intermediates, enables the tracking of reaction dynamics under changing ...
