WebElectronic Transitions 16 • Excited state molecules have different distributions of electrons, so they can have different bond strengths, bond lengths, dipole moments, pK a, etc. • Polyatomic molecules have a PES for each vibrational mode, so it’s much more complex to visualize the overall changes. • Electronic transitions use UV or ... WebIn polyatomic molecules, each bond has an individual bond moment. The dipole moment (μ) of a molecule is the vectorial addition of such bond moments. In the cases where all the individual bond moments are zero (homoatomic molecules), the resultant dipole moment is always zero. However, the converse is not true.

"WebDipole–dipole forces occur between molecules with permanent dipoles (i.e., polar molecules). For molecules of similar size and mass, the strength of these forces increases with increasing polarity. Polar molecules can also induce dipoles in nonpolar molecules, resulting in dipole–induced dipole forces. Created by Sal Khan. Sort by: Top Voted " - In case of polyatomic molecules dipole moment
