The application of the simulated ab-initio molecular orbital (SAhIO) method -a new non-empirical techniqueto the band structure of polymers is reported. The method uses full ab-initio results on small molecules to construct for polymers molecular orbitals which simulate those obtained from full ab-i

β¦ Synopsis
The sunulated ab uutxo molecular orbital (SAhIO) method IS extended to molecules amtaimng second-row atoms with d-orbltals mcluded m the basis. Results for I-butanethiol are as successful as previous studies for molecules antain& only first-row atoms. The role of hybrid orbnals is critxaIly dIscussed.

Static second hyperpolarizabilities were calculated for molecules including tetrahydrofuran homologs by ab initio molecular orbital methods at the HartreeαFock and various correlation levels. Substitution of the heteroatom with a heavier atom is found to be effective for increase of the second hyper
