Infrared inactive normal mode in C 6 H 6 has to be identified. Concept Introduction: Normal modes are independent and synchronous motion of atoms or a group of atoms that taking place in a molecule without causing the excitation of other modes. Selection rule for vibrational spectrum: During the vibration, the electric dipole moment of the molecule should change. Gross selection rule for a normal mode to be infrared activity: A normal mode is infrared active, if the motion causes the electric dipole moment of the molecule to change.
