A large peak is not expected in the IR because the symmetrical shape of the [H.sub.2][O.sub.2] molecule (H-O-O-H) does not have a significant molecular dipole moment. The small size of this peak makes it difficult to positively identify [H.sub.2][O.sub.2] by IR alone.
For example, in the most commonly used theory of microelectromagnetics, materials are averaged at a molecular level to produce effective molecular dipole moments. The microscopic EM theories developed by Jackson, Mazur, and Robinson (27), (29), (30) average multipoles at a molecular level and replace the molecular multipoles, with averaged point multipoles usually located at the center-of-mass position.
For example, in the most commonly used theory, materials are averaged at a molecular level to produce effective molecular dipole moments. When deriving the macroscopic Maxwell's equations from the microscopic equations, the electric and magnetic multipoles within a molecule are replaced with averaged point multipoles usually located at the molecular center-of-mass positions.
