Attractive Vander Waals forces occur between

Question: For a molecule to absorb IR, why must the molecule’s vibrations cause fluctuations in the dipole moment of the molecule?
[A].

Because a change in dipole moment lowers the energy required for electronic transitions

[B].

Because for absorption to occur, the radiation must interact with the electric field caused by changing dipole moment

[C].

Because fluctuations in the dipole moment allow the molecule to deform by bending and stretching

[D].

All of the above
