Effective conformations have been established for the o,o'- and m,m'-disubstituted diaryl disulfides and diselenides. Angles of aryl group rotation relative to the C-E-E plane have been determined for these compounds. One of the substituents lies inside, and one outside, the C-E-E-C dihedral angle. © 1979 Plenum Publishing Corporation.
