33 INTERMOLECULAR FORCES Polarizability and Induced Dipoles Last time we reminded ourselves of the molecular dipole mo- ment. The dipole moment is important in determined intermolecular forces and the physical properties of substances. Another equally important and somewhat related property of themo lecu leisits polarization . The polarization, α,

Unformatted text preview: f eld. An external electric f eld causes the electron cloud of a molecule to become distorted. This distortion means that, even for neutral molecules, there can exits a dipole moment. Unlike the permanent dipole moment that comes from appro-priate molecular geometry, this induced dipole is caused by the presence of the electric f eld, ε, μ = αε (33.1) INTERMOLECULAR FORCES 129...
