Multi-spectra analysis for structure elucidations have been used with machine learning, mass spectrometry, and spec-troscopy for in vitro diagnosis by Chen, X., et al. in 2023 . The use of machine learning with multiple NMR spectra has also been shown to save significant time versus manual researcher analysis of experimental spectra to predict kerogen maturity, a primary hydrocarbon source, by Kang, D., et al. .
