Charge-transfer photodissociation of adsorbed molecules via electron image states

open access: yes, 2007
The 248nm and 193nm photodissociation of submonolayer quantities of CH$_3$Br and CH$_3$I adsorbed on thin layers of n-hexane indicate that the dissociation is caused by dissociative electron attachment from sub-vacuum level photoelectrons created in the ...

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

open access: yesEPJ 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 Molecular Cloud Life Cycle. I. Constraining H2 Formation and Dissociation Rates with Observations

open access: yesThe 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

open access: yesThe 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.

Manipulating photodissociation dynamics via an embedding UV pulse

open access: yesCommunications 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

open access: yesThe 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
