Molecules that are infrared active has to be identified from the given molecules. Concept Introduction: Selection rule for vibrational spectrum: During the vibration, the electric dipole moment of the molecule should change. For homonuclear molecules, the stretching motion does not cause the electric dipole moment to change and hence are infrared inactive. For heteronuclear molecules, the stretching motion causes the electric dipole moment to change and hence are infrared active. However, not all the modes of these molecules are infrared active.
