Abstract

The use of modified virtual orbitals is studied in a systematic conventional CI procedure which offers considerable potential in regard to convergence and extension to larger systems. The method is applied to the HCN molecule by using 37 basis functions, and analysis of energy expectation values, together with the one‐electron density, yields some insight into the physical content of CI wavefunctions.

The maximization of the exchange interaction between the canonical Hartree-Fock virtual and occupied orbitals leads to a transformed set of virtual orbitals which are well suited as one-electron functions for CI calculations. The procedure, generally known for a long time is seldom applied, despite

## Abstract In this paper, a systematic procedure for synthesizing two‐terminal devices with polynomial non‐linearity is proposed. A two‐terminal, or one‐port, device with an arbitrary polynomial non‐linearity can be designed using the proposed procedure in a step‐by‐step systematic manner. A varie
