## Abstract Vicinal coupling constants of stereochemical significance were obtained in four solvents for zearalenone and specifically deuteriated zearalenone. Comparison with values calculated for several conformations using molecular mechanics calculations indicates that zearalenone exists in a si

Abstract
The complete ^1^H and ^13^C NMR spectra of the mycotoxin zearalenone are described. An analysis of all the vicinal proton–proton coupling constants, together with molecular modelling results, leads to a three‐dimensional structure very similar to those observed x‐ray crystallographically for related systems. Analogous data on zearalanone reveal that whereas the overall molecular geometry is similar to that of zearalenone, the alkyl terminus of the 12‐membered bridging moiety is now oriented almost orthogonally to the aromatic ring plane.
