    • note
    • It is assumed that the 2,2′-dimethyl-6,6′-dinitrobiphenyl group is conformationally rigid. The calculated energy profile (AMI) for 360° rotation about the central bond of the atropisomeric biphenyl is steep and shows a single pair of symmetry-related energy minima at dihedral angles approaching 90° and 270°, with a rotational barrier of ca. 35 kcal/mol.
