Conformations of Di(4-pyridyl) disulphide and Di(2-pyridyl) disulphide

Abstract

Experimental dipole moments and molar Kerr constants at 25°C are reported for di(4-pyridyl) disulphide (1.68 D, + 11 x 10^-12 e.s.u. mol^-1) and di(2-pyridyl) disulphide (3.95 D, -240x10^-12 e.s.u. mol^-1) as solutes in carbon tetrachloride. Analysis of results yields information concerning the preferred conformations of these molecules.
