## Abstract By recording two spectra of the same molecule in different nematic liquid crystals, and analysing the data simultaneously, information has been obtained on the molecular structures of 1,2,4,5‐ (1) and 1,2,3,4‐tetrachlorobenzene (2). Carbon–hydrogen and carbon–carbon internuclear distanc

## Abstract It is demonstrated that in a case where neither the proton nor the natural‐abundance ^13^C‐satellite spectra of a partially oriented molecule carry enough structural information, one can determine the entire molecular geometry by the combined use of several liquid crystals as solvents.
