Charge in JChem for Excel

Charge related custom chemical functions, including polarizability and electronegativity.

For more information, see Charge Plugin.

JCFormalCharge

Returns the formal charge of a specified atom in the input molecule.

Electronegativity

JCSigmaOrbitalElectronegativity

Returns the sigma orbital electronegativity of a specified atom in the input molecule.

JCPiOrbitalElectronegativity

Returns the electronegativity of a specified atom in the structure.

Polarizability

JCAtomicPolarizability

Atomic polarizability is altered by partial charges of atoms. Our calculation takes into account the effect of partial charge upon atomic polarizability as well as the 2D and 3D geometries. For more information, see Molecular modeling plugins.

JCMolecularPolarizability

Returns the molecular polarizability value.
