# Debye (D)

## Debye (D) Definition:

The **Debye (D)** is a unit of measure for dipole moments. 1 debye = 10^{-18} esu × cm.

## Debye (D) Explained:

A dipole moment is given as the product of the partial charge and the distance between them. Partial charges are generally on the order of 10^{-10} esu while the distance between them is generally 10^{-8}. therefore a dipole moment generally has an order of magnitude 10^{-18}, unit esu cm or 1 debye (D).

For example, 1.87 x 10^{-18} is then written or considered as 1.87 D. Measuring a Dipole unit in a compound allows us to know the ionic characteristic of a bond.
