mutual Exclusion principles.​

Answer 1

Answer:

It means that no normal modes can have both the forms( raman and infrared) at the same time. It allows us to known the symmetry element by comparison between the infrared form and active form. Example: Argon's has 1 electron in the 1s orbital and they satisfy the exclusion principle as they have opposite spins.
