• Nine chromium(III) complexes of <I>trans</I>-[CrX<SUB>2</SUB>(N)<SUB>4</SUB>] type with three kinds of optically active diamines (<I>R</I>-propylenediamine, <I>S</I>,<I>S</I>-stilbenediamine and <I>S</I>,<I>S</I>-2,4-pentanediamine) were prepared and the absorption and circular dichroism spectra were measured in the region of their d–d transitions. The CD behaviors in the spinallowed transitions were discussed in comparison with the corresponding cobalt(III) complexes and their bands were assigned to the tetragonal components. On the basis of the theoretical correlation between the rotational strengths for the spin-forbidden transitions and for the spin-allowed transitions, the CD peaks in the spin-forbidden transitions were discussed and assigned.
