A study of three smectic liquid crystal systems is made through a comparison of the high field and zero field N.M.R. spectra of probe molecules. The motional averaging of the proton dipolar interaction of a CH2Cl2 solute molecule reflects the local symmetry of Smectic A, B and E phases. In the Smectic E system, the onset of the biaxiality of the phase is clearly evident even in an unaligned sample.
