Configuration Interaction in the Calculation of Oscillatory and Rotatory Intensities of Nonplanar π-Electronic Systems

Abstract
The interaction of configurations, including all possible singly excited configurations, is incorporated into the calculation of oscillatory and rotatory intensities of simple nonplanar pi-electronic systems such as skewed butadiene and acrolein. The results are discussed in terms of the reliability of the (self-consistent field)-(linear combination of atomic orbitals)-(molecular orbital) wave functions employed.
