✦ Synopsis

35CI-NQR (77 K) spectra for some phenoxyl herbicides are reported. The frequencies are assigned to individual chlorine atoms in the molecules. The influence of substituents on the electron density distribution in the phenyl ring is discussed. Inductive, conjugative and hyperconjugative effects are analysed. The substituent constants c,,, and cp for OCH,COOH and OCHCH,COOH are estimated.
