The absorption, emission, and resonance Raman excitation profiles can be effectively modeled using equations Eqs. ( )- . The cross section units are Å2 /molecule, enabling direct comparison with experiment. Adjusting the model's parameters, {µ, ω eg , θ, ω α , S α , λ 0 , Λ}, allows the experimental profiles to be accurately fitted. Specifically, the temperature and refractive index are fixed by the experimental conditions. Initial values for the transition dipoles can be estimated from results for similar molecules and the 0-0 transition frequency, ω eg , can be approximated by the crossing point between absorption and fluorescence spectra. The solvent parameters, λ 0 and 1 Λ , are related by the ratio
