Also known as D
The debye ( , ; symbol: D) is a CGS unit (a non-SI metric unit) of electric dipole moment named in honour of the physicist Peter J. W. Debye. Likely the earliest recommendation for the Debye as a unit was in the Physikalisch-chemisches Taschenbuch (physical chemistry handbook) written by Carl Drucker and Erich Proskauer in early 1932. It is defined as statcoulomb-centimetres. Historically the debye was defined as the dipole moment resulting from two charges of opposite sign but an equal magnitude of 10−10 statcoulomb (generally called e.s.u. (electrostatic unit) in older scienti

德拜（符号为D）是一种CGS制的矢量单位。 它是偶极矩（或称电偶极矩）的非国际标准单位（。这个单位为纪念物理学家彼得·德拜而以其名字命名。德拜被定义为1×10-18 直流库伦·厘米（statcoulomb-centimeter）。德拜被定义为相距1 Å的等量（10-10直流库伦）异种电荷间的偶极矩。（在较老的文献中一般用e.s.u.，即“electrostatic unit”的缩写）。德拜是一种较为方便的分子偶极矩的单位。 一般双原子分子的偶极矩在0至11 D的範围内，对称的同原子分子，像是氯分子的偶极矩为零；而高度离子化的物质，例如气态的溴化钾之偶极矩為10.41 D。 德拜这个非国际标准单位仍在原子物理与化学中很常見，因在舊制的国际标准单位中，偶極矩的數目極大，並不方便使用。国际标准单位在2022年十一月引入了字首 q (quecto-, 10−30)，解決了這個問題，1 qC·m 約為 0.3 D。
