MODELLING OF ACIDS AND BASES REVISITED

open access: yesStudia Universitatis Babes-Bolyai Chemia, 2022
Models for dissociation and mixing of acids and bases are the main subject of many analytical chemistry textbooks. Preparing the solutions for any titration generally involves diluting acids and bases. The mathematics behind precise calculation of pH and

Cavity-Modified Unimolecular Dissociation Reactions via Intramolecular Vibrational Energy Redistribution [PDF]

open access: yesJournal of Physical Chemistry Letters, 2021
While the emerging field of vibrational polariton chemistry has the potential to overcome traditional limitations of synthetic chemistry, the underlying mechanism is not yet well understood.

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 ...

The terminator "toy" chemistry test: a simple tool to assess errors in transport schemes [PDF]

open access: yesGeoscientific Model Development, 2015
This test extends the evaluation of transport schemes from prescribed advection of inert scalars to reactive species. The test consists of transporting two interacting chemical species in the Nair and Lauritzen 2-D idealized flow field. The sources

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 ...
