Potential energy of Dipole-Dipole Interaction

V is the potential energy

μ is the dipole moment

ϵo is the vacuum permittivity.

R is the length between the two nuclei

Induced Dipoles

#Id: 8259

#Unit 1. Molecules and their Interaction Relevant to Biology

An induced dipole moment is a temporary condition during which a neutral nonpolar atom (i.e., Helium) undergo a separation of charges due to the environment.

When an instantaneous dipole atom approaches a neighbouring atom, it can cause that atom to also produce dipoles.

The neighbouring atom is then considered to have an induced dipole moment.
