The number of normal modes of vibration in linear H 2 O 2 has to be stated. Concept introduction: The complex vibrations exhibit by the polyatomic molecule is known as normal modes of vibrations. The vibrational modes of a molecule are IR or Raman active. If a molecule has centre of symmetry, then the modes which are IR-active will be Raman inactive and the modes that are IR-inactive will be Raman active. The total number of vibrational degrees of freedom for linear molecule is represented by 3 N − 5 .
