✦ Synopsis

The existence of circular dichroism in the triple differential cross section is shown for the emission of two electrons in the one-step double photoionization of a molecule. Our study reveals that the geometrical requirements for the presence of dichroic effects in the double photoionization of linear molecules are identical to those for atoms. But there are, in general, no restrictions for the presence of dichroism in non-linear molecules because it may now exist for two photoelectrons observed even with equal energies in any of the physically feasible experimental geometries. For illustration, a general procedure for studying dichroism in the double photoionization from the a~ orbital of a T d molecule is discussed.

It is demonstrated that the helic-al arrangement of dye molecules dissolved in cholestcric phases leads to a strong circular dichroism in the wavelength range of the solute absorption bands This effect yields a simple method TV determine relative polarization directions of optical transitions.
