What is Debye?

Debye is a unit of measurement named after physicist Peter Debye. This measurement applies to the moment of electric dipole and provides a standard measuring unit for these dipole moments. The symbol of this unit is D. Numerical measurement for one D is 1x10 ^-18

Specifically, Debye is a measurement of a diatomical molecule. Two hubs in the diatomical molecule are separated by the distance of one angstrom. Both hubs have a measurement of 10 -10 Franklins or statcoulombs.

The diatomical molecules that has the same molecules such as oxygen gas (o _{2 ), hydrogen gas (H 2 ) and chlorine gas (CL 2 ) do not have the moment of the dipole. Molecules with more than two atoms will not behave no dipole torque if the atoms are located in a linear arrangement, such as carbon dioxide molecule (CO 2 ). Symmetrical molecules such as methane (ch 4 ) will also have no dipole moment.}

The torque of the dipole will depend on the atoms in the molecule and the arrangement or structure of these atoms. Molecules containing two different atoms such as hydrochloric acid (HC1) will have a dipole torque. Other dipo moments molecules are molecules that have a bent or angular arrangement. Water (H _{2 o) is a good example of a bent structure. The angle formed by two oxygen -bound hydrogen molecules is 107.5 degrees.}

D is not a unit of SI, an aletentimeter gram secondary (CGS) unit. If dipole moments are measured using units of SI, the resulting numbers are very large. Instead of units, this measurement was developed to keep the numbers small, whichObviously the calculations are less cumbersome.
