Unit | Symbol | Symbol (plain text) | Value | Notes |

debye | Show source$D$ | D | 1 | Unit of dipole moment derived from the centimeter-gram-second system (CGS). One debye corresponds to a dipole moment occurring between two charges of one ten billionth franklin (10^{-10} Fr) separated by distance of one agstrem (1 Å). Although the CGS system has been displaced by SI units, the debye unit is still often used in atomic physics and to determine the dipole moment of chemical molecules. This fact has purely practical reasons, because most chemical molecules have a dipole moment within range 0-11 debyes.$1\ D = 10^{-10}\ Fr \cdot \text{Å} \approx 3.33564 \cdot 10^{−30}\ C\ \cdot m$ |

atomic unit of electric dipole moment | Show source$au$ | au | 0.393430307 | Unit of dipole moment often used in quantum-mechanical calculations. One atomic unit corresponds to a dipole moment between two elementary charges (e) spaced apart by a distance of one Bohr radius (a_{0}).$1 au = e \cdot a_0 \approx 8.478 353 6255 \cdot 10^{-30}\ C \cdot m$ |

# Some facts#

- The
**electric dipole moment**for a system consisting of two or more**point charges**is defined as the below sum:

$\overrightarrow{p} = \sum_{i=1...n}{q_i \overrightarrow{r_i}}$where:

**$\overrightarrow{p}$**- electric dipole moment of the whole system,

**$\overrightarrow{r_i}$**- a vector pointing to the i-th electric charge,

**$q_i$**- value of i-th charge,

**$n$**- number of charges in the system.

- Dipole moment is a
**vector**. - The dipole moment makes sense for
**neutral systems**, i.e. where the sum of all charges is zero:

$\sum_{i=1...n}{q_i} = 0$ - The unit of electric dipole moment in SI system is
**coulomb times meter**:

$C \cdot m$ - Another unit, used mainly by chemists and atomic physics, is
**1 debye**:

$1 D = 3,33564 \cdot 10^{-30} C \cdot m$ - If the system with the dipole moment $\overrightarrow{p}$ is introduced into the external electric field $\overrightarrow{E}$, then the moment of force will act on it is:

$\overrightarrow{M} = \overrightarrow{p} \times \overrightarrow{E}$ - Molecules with
**non-zero dipole moment**are called**polar**. An example of such a molecule is water ($H_2O$). - If the electric charges in the system are
**evenly distributed**, then the dipole moment of such a system is zero. Examples of such systems are**chemical molecules with a symmetrical structure**such as carbon tetrachloride ($CCl_4$). Such molecules are called**apolar**or**non-polar**.
