Elucidating the Three-Dimensional Structure of Piracetam through Rotational Spectroscopy. [PDF]
ChemistryOpenNeutral molecules of the nootropic drug piracetam are generated by laser ablation and structurally characterized by microwave spectroscopy. Two conformers differing in the exo/endo configuration of the pyrrolidine ring are detected, with exo being the predominant form.

Sustainable and Simple Water-Induced Separation of Ionic Liquid Mixtures. [PDF]
Angew Chem Int Ed EnglThe cover image illustrates an innovative method for recovering ionic liquids (ILs) from their mixtures. This approach enables the recovery of over 99% of the IL by simply adding water–abundant, and safe solvent–under mild conditions, all while preserving the integrity of the ILs.

Rotational Spectroscopy as a Tool to Characterize Sweet Taste: The Study of Dulcin. [PDF]
ChemistryOpenWe provide experimental evidences that support the old theories of sweetness using dulcine as the archetypal molecule by means of Laser Ablation Chirped Pulse Fourier Transform Microwave Spectroscopy (LA‐CP‐FTMW) technique. Eluciding the structure of dulcin, we can decipher if it meets the structural requirements that a sweet molecule need to have ...

Transferable Semiempirical Models for Judd-Ofelt Parameters and Multiphonon Relaxation in Eu<sup>3+</sup> Complexes: Toward an Experiment-Free Luminescence Design. [PDF]
J Comput ChemABSTRACT The rational design of lanthanide‐based luminescent systems using purely theoretical approaches remains challenging due to the reliance of existing models on experimental data. Herein, we propose a theoretical protocol for the design of new Eu3+ based luminescent systems, starting from a previously synthesized and experimentally characterized ...
