Abstract

In the present work we have studied the changes in the FWM signal response considering the modification in the longitudinal and transversal relaxation times T₁ and T₂, respectively. These changes are obtained considering three cases of rate between longitudinal and transversal relaxation times T₁/T₂, with three orders of magnitude between them: a) 0.1, b) 1 and c) 10. These modifications are applied to push-pull molecules, taking into account the valence-bond charge-transfer model. Moreover, we have taken into account the symmetric values of V_o = ± 1 (corresponding to the electronic energy gap between the states involved in the model). Notable changes in maximal intensity of the peaks belong to the FWM spectrum are observed with the variation in the ratio between the relaxation times.
