Sigma*-mediated electronic relaxation in 200nm photoexcited ammonia and heteroaromatics

EPJ Web of Conferences, 2013
Time–resolved photoelectron spectra of ammonia display combination bands of the umbrella and stretching modes associated with the N–H coordinate of σ* relaxation. Time–resolved photodissociation studies determine timescales

The chemistry of fluorine-bearing molecules in diffuse and dense interstellar gas clouds

, 2005
We present a theoretical investigation of the chemistry of fluorine-bearing molecules in diffuse and dense interstellar gas clouds. The chemistry of interstellar fluorine is qualitatively different from that of any other element, because - unlike the ...

The Molecular Cloud Life Cycle. I. Constraining H2 Formation and Dissociation Rates with Observations

The Astrophysical Journal
Molecular clouds (MCs) are the birthplaces of new stars in galaxies. A key component of MCs are photodissociation regions (PDRs), where far-ultraviolet radiation plays a crucial role in determining the gas’s physical and chemical state.

TIRAMISU: Non-LTE Radiative Transfer for Molecules in Exoplanet Atmospheres

The Astrophysical Journal
The TIRAMISU code, a new program for computing on-the-fly non-LTE molecular spectra and opacities for solving self-consistent radiative transfer problems in exoplanet atmospheres, is presented.

Wavelength-dependent photodissociation of iodomethylbutane

Scientific 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 ...

Manipulating photodissociation dynamics via an embedding UV pulse

Communications Physics
Ultraviolet (UV) photodissociation provides valuable insights into fragmentation patterns and photochemical reactions. However, the limited overlap between vibrational bound states and continuum states hinders efficient quantum excitation.

Photoionization and Photodissociation Rates across a Solar Cycle

The Planetary Science Journal
Unattenuated photoionization and photodissociation rate coefficients are calculated using solar spectral irradiance measurements across a continuous solar cycle spanning 2004–2014. These rates are organized by corresponding daily F _10.7 P indices, where
