Photodissociation of long-range Rydberg molecules [PDF]
Phys. Rev. A 102, 062819 (2020), 2020 We present photodissociation of ultracold long-range Rydberg molecules as a tool to characterize their electronic properties. We photoassociate K2 37P molecules with highly entangled electronic and nuclear spins of the two bound atoms and quantify the entanglement by projection of the molecular state onto non-interacting atoms using radiofrequency ...

ExoMol photodissociation cross sections I: HCl and HF [PDF]
, 2022 Photon initiated chemistry, \textit{i.e.} the interaction of light with chemical species, is a key factor in the evolution of the atmosphere of exoplanets. For planets orbiting stars in UV-rich environments, photodissociation induced by high energy photons dominates the atmosphere composition and dynamics.

Mass Spectrometry Reviews, EarlyView., 2023 Abstract Analysis of triacylglycerol (TG) and phospholipid sn‐positional isomers can be divided into two main categories: (a) direct separation by chromatography or other means such as ion mobility mass spectrometry and (b) quantification of regioisomer ratios by structurally informative fragment ions with mass spectrometric methods.

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

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

Host‐guest tuning of the CO2 reduction activity of an iron porphyrin cage
Natural Sciences, Volume 3, Issue 1, January 2023., 2023 An iron porphyrin cage can catalyze CO2 electroreduction to CO with a large selectivity. The catalytic properties can be further improved by tuning the internal electrostatic potential of the cage by hosting the potassium ions in the crown‐ether‐like side walls.

Vibrationally mediated photodissociation dynamics of pyrrole
AIP Advances, 2019 We investigate photodissociation of vibrationally excited pyrrole molecules in a velocity map imaging experiment with IR excitation of N–H bond stretching vibration v1 = 1, νIR= 3532 cm−1, and UV photodissociation at λUV= 243 nm. In the IR+UV experiment,
