WebJan 30, 2024 · Microwave rotational spectroscopy uses microwave radiation to measure the energies of rotational transitions for molecules in the gas phase. It accomplishes this through the interaction of the electric dipole moment of the molecules with the electromagnetic field of the exciting microwave photon. Introduction WebThe gross selection rule for a molecule to be IR active and show vibra-tional transitions is that it should have a dipole moment that changes as the molecule vibrates. For a diatomic molecule, there is only one vibrational mode. If the molecule is homonuclear, then it cannot be IR active whereas if it is heteronuclear, it can be IR active.
