The website offers detailed articles on topics like covalent bonds, electron configurations, and the pH levels of common substances like apples and bananas. It also provides insights into the molecular structures, hybridization, bond angles, and shapes of various chemical compounds, such as Phosphorus...
To this end, we propose a novel geometry-enhanced molecular representation learning method (GEM). First, to make the message passing sensitive to geometries, we model the effects of atoms, bonds and bond angles simultaneously by designing a geometry-based GNN architecture (GeoGNN). The architectur...

5). Ab initio calculations indicate that the C–H⋯O hydrogen bond between Cα–H groups of amino acids and water molecules is about half as strong as a classical one between two water molecules (Scheiner et al., 2001). Likewise, a Cα–H⋯OC interaction (of energy −2.1 kcal/...
