Linear and Two‐Dimensional Infrared Spectroscopy of the Multifunctional Vibrational Probe, 3‐(4‐Azidophenyl) Propiolonitrile. Deperturbing a Fermi Triad by Isotopic Substitution

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Linear infrared spectroscopy combined with isotope labeling and density functional theory unravels the origin of a Fermi triad in a multifunctional vibrational chromophore. Ultrafast 2DIR‐spectroscopy reports directly on the dynamics and the intramolecular vibrational energy flow pathways in the isotopically deperturbed system. Abstract Infrared probes

When Dihedral Angles Mask Denticity in Molecular Conductance

open access: yesChemPhysChem, EarlyView.
This study tests whether higher molecule–electrode denticity increases conductance in single‐molecule junctions. Using nonequilibrium Green's function technique in conjunction with density functional theory simulations and mechanically controlled break‐junction experiments on a tetradentate N‐heterohexacene, it is found that conductance depends mainly ...

Ligand Field Tuning of Photoreactivity: Contrasting Low‐Spin and High‐Spin Fe(III)‐Azido Complexes

open access: yesChemPhotoChem, EarlyView.
Why do near‐identical Fe(III)‐azido complexes exhibit different photoreactivity profiles? Linking spin states and key normal modes to wavelength‐dependent photoreductive and photooxidative reaction paths shows how supposedly minor structural changes influence the spin ground state, in turn dictating the photoreactivity profile of the complexes.

Modeling the Probability of Tsunami Fire Ignition Based on Data From the 2011 Tohoku and 2024 Noto Peninsula Earthquakes, With Recommendations to Reduce Emerging Fire Risk in Tsunami Vertical Evacuation Structures

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Recent tsunamigenic earthquakes in Japan have highlighted the emerging fire hazard triggered by tsunami inundation and its impact on tsunami vertical evacuation (TVE) structures. This new type of fire following earthquake, referred to as “tsunami fires,” may be a potential universal hazard that tsunami‐prone countries face; however, it has not

The prevalence of food insecurity and its relationship with wellbeing in a large, cross‐sectional study of children and young people in England

open access: yesJCPP Advances, EarlyView.
AbstractBackgroundWe aimed to assess the prevalence of food insecurity reported by children and young people in four areas of England in 2023 and examine its association with mental health and wellbeing.MethodsWe used data from the OxWell student survey, a large, diverse, cross‐sectional study of 38,430 students aged 8–19 years, conducted primarily in ...
