WebMar 28, 2024 · As quantum chemical properties have a significant dependence on their geometries, graph neural networks (GNNs) using 3D geometric information have achieved high prediction accuracy in many tasks. However, they often require 3D geometries obtained from high-level quantum mechanical calculations, which are practically infeasible, limiting … WebIn chemistry, a pyramid refers to molecular geometry, or, to put it another way, the structure of compounds, including bond lengths, angles, and so on. When we think of pyramids, we usually think of trigonal bipyramidal, which are molecules that have a pyramid-like shape with a triangle base. A trigonal pyramid has one atom at the apex and ...
