UV Luminance Spectroscopy - Medical Science

Q1:

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

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