Paper Abstract

The solvatochromic behaviour of several nonlinear optical (nb) chrornophores, synthesised following the discovery of the novel reaction of triethylamine with tetracyano-p-quinodiniethane (TCNQ)" 2 is investigated. An alternative method of calculating the static first hyperpolarisability, J3 is proposed for molecules that exhibit anomalous solvatochromic behaviour, where it is difficult to apply standard solvatochromic models. Values of f3 are estimated from this data using both spherical and ellipsoidal local field models, where difficulties in the calculations are highlighted. The relative merits of these models are discussed with particular attention paid to the calculation of the cavity radius.
