A model is presented which allows to obtain a linear relationship between infrared and Raman intensity parameters of the strongest vibrational bands of push–pull conjugated molecules. The results obtained clarify the origin of the exceptionally large values of the vibrational first hyperpolarizability shown by these molecules.

Abstract
A model is presented which allows to obtain a linear relationship between infrared and Raman intensity parameters of the strongest vibrational bands of push–pull conjugated molecules. The results obtained clarify the origin of the exceptionally large values of the vibrational first hyperpolarizability shown by these molecules.File in questo prodotto:
