The NMR spectra of a number of octadecadiynoic acids and of the derived cis, cis-and trans, trans-octadecadienoates have been studied using a 100 MHz instrument. Characteristic spectral features associated with the number of methylene groups between the two unsaturated centres are described. In diun
