Unit Conversion

1 Debye = 3.336 × 10³° C·m

1 Debye = 10¹&sup8; esu·cm

Calculation

μ = q × d
μ = 1.6000e-10 C × 1.0000e-10 m
μ = 1.6000e-20 C·m = 4796163069.5444 D

Understanding Dipole Moments

The dipole moment (μ) is a measure of the separation of positive and negative charges in a system. It is calculated as the product of the charge magnitude and the distance between the charges. The Debye (D) is the most common unit for molecular dipole moments, named after physicist Peter Debye. Molecules with larger dipole moments are more polar and have stronger intermolecular forces.
