The complete r_s structures for both 1,1- and cis-1,2-dichloroethenes have been derived from isotopic measurements for each isotopic position.The accuracy of the structural parameters obtained is discussed on the basis of isotope effect on bond lengths caused by zero-point vibrations, and it is suggested that more than 0.01 Angstroem of additional uncertainty originating from the isotope effect must be considered for the bond lengths determined by means of the Kraitchman method.The quadrupole coupling constants are re-evaluated by use of the newly determined structures.
