In the present paper, we report the quantitative evaluation of the electron density shift (EDS) maps within different complexes. Values associated with the total EDS maps exhibited good correlation with different quantities such as interaction energies, Eint , intermolecular distances, bond critical points, and LMOEDA energy decomposition terms. Besides, EDS maps at different cutoffs were also evaluated and related with the interaction energies values. Finally, EDS maps and their corresponding values are found to correlate with Eint within systems with cooperative effects. To our knowledge, this is the firsttime that the EDS has been quanitatively evaluated.

Evaluation of electorn density shifts in noncovalent interactions

@LatinXChem is a virtual forum through which the community of Latin American chemists, located anywhere in the world, can share and discuss their research results and advances. More than 1200 posters from 43 countries were received in its first version, with 20 million impacts on Twitter. The second event organized by @LatinXChem will be the #LXChem2021 Conference (September 20, 2021), where posters divided into eleven categories can be discussed via Twitter.
