1H NMR-Based Framework for Estimating Molecular Formation Enthalpies of Organic Compounds
We report a method for estimating standard enthalpies of formation (ΔHf°) directly from routine 1H NMR spectra. By combining spectral features with heteroatom-based functional motifs, accurate models were obtained (R2 ≈ 0.99; RMSE ≈ 5.5 kcal mol–1). The predictive performance was consistent across multiple validation...
