1 H NMR spectroscopy was used as a rapid method of determining the amount of the three possible isomeric forms of bisphenol‐F diglycidyl ether, one of the basic materials of epoxy resins for industrial applications. The complete spectral analysis of the glycidyl group, with respect to chemical shifts, coupling constants and magnetic anisotropy, made it possible to separate the overlapping signal regions by computational spectral simulation. Partial separation could also be obtained by application of the ‘Aromatic Solvent Induced Shift’ effect. A combination of both methods has been used successfully for the quantitative determination of the isomeric ratios of commercially available bisphenol‐F diglycidyl ethers.
