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

## Abstract Using a 6โ311G\*\* basis set with estimation of correlation energy at the MP2 level, structural and energetic data for 40 molecular species containing magnesium have been calculated. For about half the species studied, further energetic data were obtained using Pople's G2 method. Enthal
