Abstrakt: 1.It was established by the PMR method that a two-component conformational equilibrium with approximately equal proportions of the trans and gauche rotamers is realized in solutions of the investigated ß-halogenophenetoles in carbon tetrachloride.2.The procedures for the empirical calculation of the3JHH constants are identically effective for the investigated compounds.3.The spectral parameterA=N+1/3¦L¦ varies with variation of the temperature and the dielectric constant of the medium.
