The reaction and measurement started immediately after the catalyst was added. However, the addition was performed outside the magnet, and thus, the first several spectra have distorted intensities due to insufficient spin polarization. As mentioned above, there was also no time for proper shimming, and the magnetic field stabilization (locking) was impossible due to the lack of deuterated solvent. Thus, in all spectra lineshapes were distorted and deviated far from the usual Lorentzian/Gaussian functions, thus the deconvolution or peakfitting would not be accurate. Still, the peaks in the spectra of 2-pentene hydrosilylation were quite well resolved, allowing the simple integration (region-wise summation), whose results match very well with the Magnetstein output (see Fig. ). The more difficult case was the hydrosilylation of 1-hexene, which provided spectra with complete overlap of product and substrate peaks. As shown in Fig. , the conventional integration gives the results differing from the Magnetstein output. Namely, the overlap of integrated product and substrate peaks leads to flattening of sigmoidal kinetic curves (one can imagine, that in the extreme case of a full overlap, the kinetic curve would be a constant function). The Magnetstein tool, however, has demonstrated robustness to such peak overlaps in previous studies. This advantage stems from its reliance on optimal transport which provides a mathematical framework that treats the redistribution of spectral intensity as a flow between defined regions, analogous to redistributing a resource efficiently from one area to another. By jointly analyzing the spectral regions as part of a global optimization, Magnetstein allows for the "movement" of spectral intensity across overlapping peaks in a way that respects the overall conservation of intensity.
