An induced dipole is a dipole created in a molecule by the influence of a nearby charge or dipole, which distorts the molecule's electron cloud. The more easily a molecule's electrons are distorted (the more polarisable it is), the larger the induced dipole. Induced dipoles give rise to dispersion forces and to ion–induced and dipole–induced dipole attractions.

诱导偶极是在邻近电荷或偶极的影响下、因分子电子云发生畸变而在分子中产生的偶极。分子的电子越容易被畸变(即极化性越强),诱导偶极越大。诱导偶极产生色散力以及离子–诱导偶极和偶极–诱导偶极吸引。
