|Physical quantity (s)||Electric dipole moment|
|system||Electrostatic CGS unit system , Gaussian CGS unit system|
|In CGS units|
|Named after||Peter Debye|
|Derived from||Franklin (unit) , centimeter|
As Debye [ dəbɛi̯ə ] ( unit symbol D ; by Peter Debye , the explorer of the dipole phenomena) refers to the CGS unit of the electric dipole moment in the gaussian system of units and in the electrostatic unit system (ESU) .
with for the Ångström .
Since the use of the coulomb meter leads to very small numerical values on atomic scales, the Debye is usually used.
In addition, the following approximation applies:
- for the elementary charge .
