Abstract
A conformational study of 5,5'-bis-(1,3,6-trimethyluracylyl)methane (1 ) is carried out using molecular orbital calculations (AMI), molecular mechanics, dipole moment, and electric birefringence methods. The AM1 calculations result in good agreement with the experimental data. Pop ulations of the helical steady states and the ways of their interconve rsion are determined. Dipole moments, Kerr's constants, optical anisot ropies of the title compound, and some related 1,3-dimethyluracyls are measured.
