  In spectroscopy: Vibrational energy states

  …0, 1, 2,… is the vibrational quantum number, ν₀ = (1/2π)(k/μ)^1/2, and k is the force constant of the bond, characteristic of the particular molecule. The necessary conditions for the observation of a vibrational spectrum for a diatomic molecule are the occurrence of a change in the…
