Observing the 3D Chemical Bond and its Energy Distribution in a Projected Space

Area of Science:

• Chemistry
• Materials Science
• Quantum Mechanics

Background:

• The long-standing desire to visualize chemical bonds is enhanced by advances in electron charge density analysis.
• Current understanding of molecules and materials is heavily reliant on bond-centric models.

Purpose of the Study:

• To present a new method for analyzing chemical bonds and their energy distributions.
• To objectively analyze bond formation and recontextualize existing bonding models.

Main Methods:

• Developing a two-dimensional projected space termed condensed charge density.
• Utilizing bond silhouettes in condensed charge density to identify three-dimensional bond bundles.
• Reverse-projecting bond silhouettes to precisely define bonding regions.

Main Results:

• Demonstrating objective analysis of both delocalized metallic and organic covalent bonds.
• Observing the formation of chemical bonds through the condensed charge density.
• Rationalizing the crystallographic structure of simple metals using bond bundle structure.

Conclusions:

• The presented method provides a new perspective on chemical bonding through electron charge density.
• This approach allows for objective analysis and observation of bond formation.
• It offers a framework to re-evaluate and understand chemical bonds in molecules and materials.
