UV Luminance Spectroscopy

For a molecule to absorb IR, why must the molecule's vibrations cause fluctuations in the dipole moment of the molecule?

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

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

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

All of the above
