Probing electron localization during molecular dissociation by femtosecond strong-field ion momentum spectroscopy

open access: yesCommunications Physics, 2023
The study of molecular valence electron dynamics and their coupling with nuclear motion is one of the frontiers of ultrafast physics and ultrafast chemistry. With time-resolved strong-field ion momentum spectroscopy, we study electron valence and nucleus

Impact of acidity and surface-modulated acid dissociation on cloud response to organic aerosol [PDF]

open access: yesAtmospheric Chemistry and Physics
Acid dissociation of the organic aerosol fraction has the potential to impact cloud-activating properties by altering aqueous-phase H+ concentrations and water activity but is currently overlooked in most atmospheric aerosol models.

The Roasting Marshmallows Program with IGRINS on Gemini South I: Composition and Climate of the Ultrahot Jupiter WASP-18 b

open access: yesThe Astronomical Journal, 2023
We present high-resolution dayside thermal emission observations of the exoplanet WASP-18 b using IGRINS on Gemini South. We remove stellar and telluric signatures using standard algorithms, and we extract the planet signal via cross-correlation with ...

Hypervelocity Richtmyer–Meshkov instability [PDF]

open access: yes, 1997
The Richtmyer-Meshkov instability is numerically investigated for strong shocks, i.e., for hypervelocity cases. To model the interaction of the flow with non-equilibrium chemical effects typical of high-enthalpy flows, the Lighthill-Freeman ideal ...

Quantum Dynamics of Exciton Transport and Dissociation in Multichromophoric Systems.

open access: yesAnnual review of physical chemistry (Print), 2021
Due to the subtle interplay of site-to-site electronic couplings, exciton delocalization, nonadiabatic effects, and vibronic couplings, quantum dynamical studies are needed to elucidate the details of ultrafast photoinduced energy and charge transfer ...
