The analysis of the 13 C NMR spectra of several 2,3,6,7‐tetraalkoxy‐9,10‐dihalomethyl‐9,10‐dihydroanthracenes showed a strong dependence of the chemical shift values on the orientation of the halomethyl groups. On this basis it was possible to determine both the configuration ( cis or trans ) and conformation of the isomers, even if only one isomer was available.
