Extending the Applicability of the Semi-experimental Approach by Means of 'Template Molecule' and 'Linear Regression' Models on Top of DFT Computations

Autor: Cristina Puzzarini, Francesca Tonolo, Alessio Melli, Vincenzo Barone

Publikováno v: The Journal of Physical Chemistry. a

The accurate determination of equilibrium structures for isolated molecules plays a central role in the evaluation and interpretation of stereoelectronic, thermodynamic, and spectroscopic properties. For small semi-rigid systems, state-of-the-art qua

Unveiling Bifunctional Hydrogen Bonding with the Help of Quantum Chemistry: The Imidazole-Water Adduct as Test Case

Autor: Cristina Puzzarini, Vincenzo Barone, Alessio Melli

Publikováno v: The Journal of Physical Chemistry. a

The ubiquitous role of water and its amphiprotic nature call for a deeper insight into the physical-chemical properties of hydrogen-bonded complexes formed with building blocks of biomolecules. In this work, the semiexperimental (SE) approach combine

Theory meets experiment for elucidating the structure and stability of non-covalent complexes: Water-Amine interaction as a proof of concept

Autor: Vincenzo Barone, Yang Zheng, Junhua Chen, Qian Gou, Lorenzo Spada, Alessio Melli, Gang Feng, Cristina Puzzarini, Tao Lu

Several gas-phase spectroscopic investigations have focused on a better understanding of the nature of weak, non-covalent interactions in model systems. However, their characterization and interpretation are still far from being satisfactory. A promi
