Highly Sensitive, Low‐Cost Deep‐UV Resonant Raman Microspectroscopy Systems

open access: yesChemistry–Methods, EarlyView.
Low‐cost deep UV resonant Raman microscope for chemical sensing and imaging has been developed and its performance has been experimentally validated for several potential applications. Multimodal imaging capabilities of a new instrument have been demonstrated as well.

iSELECTION: An Instrument to Study the Kinetics of Isomer‐Selected Gas‐Phase Ion‐Molecule Reactions

open access: yesChemistry–Methods, EarlyView.
Isomer‐specific reactivity is key in cluster chemistry. Herein, it is shown that how combining drift‐tube ion mobility with mass spectrometry enables the derivation of reaction rate coefficients for coexisting C40+$\text{C}_{40}^{+}$ isomers, opening new avenues for studying complex chemical systems ...

eChem: Accelerated Method Development in Quantum Chemistry with Notebooks

open access: yesChemistry–Methods, EarlyView.
The benefits of using Jupyter Notebooks to simplify and accelerate scientific code development are demonstrated using the practical example of the analytical molecular Hessian. The eChem project has been previously presented as an interactive platform for quantum and computational chemistry education [J. Chem. Educ. 100, 1664–1671].

UV–Vis Spectra of Carbonic Acid: Rationalizing Experimental Redshifts between Monomer and Bulk based on (H2CO3)n Calculations

open access: yesChemPhysChem, EarlyView.
In bulk carbonic acid (e.g., in interstellar icy dust grains) cluster formation produces two distinct UV‐Vis spectral features redshifted by ≈2 eV (25 nm) and by ≈5 eV (80 nm) compared to gas phase single molecule carbonic acid 's adiabatic ionization energy. Theory and experiment were used to investigate the origin of these shifts.

Symmetric Bis‐Kryptopyrrol‐2‐Yl Squaraine as a Viscosity Probe and Dual‐State Emitter

open access: yesChemPhotoChem, EarlyView.
Previously unknown capabilities of one of the original squaraine dyes as a viscosity probe and dual‐state emitter are revealed, with aggregated forms of the dye being responsible for the near‐IR emission in the solid state. Easily accessible small organic fluorophores with multiplexing capabilities are of interest for a variety of fields.
