When analyzing complexes 1 and 2, it has been observed that the peak energies for both pre-and rising-edge reasons tend to be similar, as shown in Figure . To further improve the BIC and AIC criteria while maintaining an acceptable MSE, it would make sense to test a global fitting model for both complexes together. However, before starting the fit, it should be noted that both spectra will be combined and then reshaped back into two again.
