The rotational Raman spectrum of a diatomic molecule has the first line of a series of Stokes and anti-Stokes lines at , relative of the
of incident light. What would be its bond length.
In atomic and molecular spectroscopy, the rotational Raman spectrum arises due to the inelastic scattering of light by molecules, where the energy of the scattered photons corresponds to transitions between rotational energy levels.
