Dispersion on NLO properties

Experimental data on dispersion of the complex third-order nonlinear susceptibility of organics and organometallics are still very scarce despite being crucial for any assessment of the suitability of these materials for applications using their nonlinear absorption and/or nonlinear refraction. We are trying to improve the situation. Here are a few papers relating to the subject:
