#Unit 1. Molecules and their Interaction Relevant to Biology
Dipole-Dipole Interaction
Dipole-Dipole interactions occur between molecules that have permanent dipoles; these molecules are also referred to as polar molecules.
#Id: 8255
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

The negative sign indicates that energy is released out of the system, because energy is released when bonds are formed, even weak bonds.

Induced Dipoles
#Id: 8259
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.
