Once the HERFD-XAS of complex 1 fitting is completed, the same input guess is utilized for the absorption spectra of complex 2 (Figure -middle plot). After fine-tuning, the results appear to be sufficiently accurate, precluding any further optimizations. Here, the primary benefit of Jupyter (Figure -bottom plots) is to provide the user with a playground to explore the data and also to tell insightful stories out of the data due to its didactic potential. Through the utilization of data-driven storytelling techniques, three dominant peaks in both spectra spanning a range from 7110 to 7116 eV have been successfully identified. All three peaks were found to be in close proximity to each other, with an energy difference of less than 0.14 eV through independent fits. Peaks I and II were associated with transitions from the 1s core hole to the 3d manifold , while peak III of complex 2 was previously thought to be a metal-to-metal charge-transfer (MMCT) transition. The Gaussian distribution used for the assumed MMCT transition can also be applied to the fitting model of complex 1, which is interesting. In terms of amplitude comparison, a significantly more substantial variation was exhibited by mixed-valence complex 2 than complex 1, although their mean values were similar with a difference of approximately 10%.
