In addition to 1D NMR methods and 2D shift-correlated NMR techniques (COSY and HETCOR), spin-spin simulation and MMX calculations, to obtain the minimum energy conformation structure, were used for the complete 1 H and 13 C NMR assignments of stephalic acid.

Abstract
^1^H, ^19^F and ^13^C chemical shift assignments and ^1^H–^1^H, ^1^H–^19^F, ^19^F–^19^F and ^19^F−^13^C coupling constants for nine 5,7‐dihalogenated kynurenic acid derivatives are reported. Data and assignments are based on 1D and 2D NMR experiments.
