Abstract. A theoretical link based on two-level system is developed that permits the estimation of third-order hyperpolarizabilities from parameters measured by linear spectroscopic techniques of Raman resonance and absorption spectroscopy. In an attempt to gain experimental evidence for the proposed link, we have examined β-carotene in different organic solvents.
