Our electron distribution analysis service offers researchers and pharmaceutical companies a powerful tool to investigate electronic properties, chemical reactivity, and molecular interactions with high precision.
Introduction to Electron Distribution
Electron distribution describes how electrons are arranged around an atom's nucleus or within a molecule. In atoms, electrons occupy specific energy levels and orbitals following rules like the Aufbau principle. In molecules, electron distribution affects chemical bonding. Uneven distribution can lead to polar bonds and influence molecular reactivity. Understanding electron distribution helps explain properties such as conductivity, solubility, and chemical behavior. It's fundamental to grasping chemical reactions and molecular structures.

Our Services
Accurate electrical property analysis forms the cornerstone of technological advancement. CD ComputaBio offers a series of meticulously designed services to meet the diverse needs of clients.
Electron Density Analysis
3D electron density is provided maps to identify nucleophilic/electrophilic sites and analyze chemical reactivity. Using Laplacian of electron density, we distinguish covalent, ionic, and van der Waals interactions. Our QTAIM (Bader's Quantum Theory of Atoms in Molecules) analysis locates bond critical points, offering deep insights into molecular structure and stability.
Molecular Orbital Analysis
CD ComputaBio computes HOMO-LUMO orbitals to predict reactivity and stability through frontier orbital theory. The HOMO-LUMO energy gap reveals electronic properties, while localization/delocalization analysis explains conjugation effects in aromatic and conducting systems.
Electrostatic Potential (ESP) Mapping
ESP maps we offered highlight electrophilic/nucleophilic regions for reaction prediction. Combined with non-covalent interaction (NCI) analysis, we identify hydrogen bonds and steric effects critical for drug binding and material design.
