Absorption frequencies

Use Coringuration Interaction to predict electronic spectra of molecules. The Con ngiiration Interaction wave function provides a ground state plus soin e excited state energies. You can obtain electron ic absorption frequencies from the differences betw een the energies of the ground state and the excited states.

The authors (85) have also mentioned the deformational vibrations (7) of the out-of-plane group -CH= of a pentatomic heterocyclic nucleus, showing that there exists a relationship between the absorption frequencies of this group and the electronegativity of the heteroatom (86).
