Differential Charge Density Calculation
Differential Charge Density
Differential charge density is the difference in electron density between the two states of a system. By comparing the charge densities of ground and excited states or different configurations, researchers can determine the location and magnitude of electronic charge redistribution. Differential charge density calculations are an important aspect of first-principles calculations in computational chemistry and materials science.
Methods
CD ComputaBio offers several methods to calculate the differential charge density of a system. These methods include the finite difference method, the perturbation theory method, and the linear response method.
Services Items
At CD ComputaBio, we offer differential charge density calculation services for a wide range of systems, including but not limited to molecules, surfaces, nanoparticles, and bulk materials. Our services include
- Total differential charge density calculations: We calculate the total differential charge density between ground and excited states or different configurations. This information helps researchers understand the redistribution of electronic charges and the underlying chemical bonds.
- Local differential charge density calculations: We perform local differential charge density calculations to determine the charge distribution around a particular atom or group of atoms.
- Charge transfer analysis: We determine the degree of charge transfer between different parts of a system by analyzing differential charge densities.
