Notes:
Model calculations of the absorption and the four quantities representing third-order non-linear susceptibility [the real and imaginary part of the excitation profile and of the resonance background component for resonance coherent anti-Stokes Raman scattering (CARS), R, J, b′ and b″, respectively] were carried out for polyatomic molecules. Comparison with previously acquired experimental data for bisdimethylaminoheptamethine perchlorate shows satisfactory agreement, except for b′ and b″. Some molecular parameters (the shift parameter of the active vibrations and the vibronic relaxation constant) were estimated. It is concluded that the resonance background is more sensitive to the model than the absorption and the excitation profile.
