In this work we study the changes in the Four-Wave Mixing (FWM) signal with the modification of the permanent and transition dipolar moments of states in a coupled basis (under the inclusion of intramolecular coupling phenomenon), due to the changes in different parameters, such as coupling parameters v and Vo, strength constant δ, and transition dipolar moment between the uncoupled states m12. Changes in the intensity and position of the resonances in the FWM signal spectra are observed with the variation in the parameters mentioned above.
