   Abstract:
   The absolute configuration of 1,3,5,7-tetramethyl-1,3-dihydroindol-2-one was determined by quantum chemical calculations of specific rotation angles with coupled-perturbed Hartree-Fock methods. The computation used molecular geometries obtained from ab initio calculations as well as from molecular mechanics and semi-empirical optimization. In addition to the dependence on geometry optimization strategies, the basis set dependence of the computed rotation angle was examined.
