Özet

In context of insulation and environmental properties, decomposition products in SF6-N-2 mixtures in the presence of H2O are analyzed by Density Function Theory (DFT). Homo and Lumo structures of ten decomposition products are given with the optimized geometries employing B3LYP hybrid method at the 6-311+G(d,p) level. The presented information with respect to the electronic states, ionization energies and energy gaps of SOF4, SO2F2, SOF2, S2F10, S2O3F6, and (SF5)(2)NF decomposition products is not available in the literature. Ionization energies, electron affinity and molecular orbital energy gap which is an indicator of the stability of the by-products are reported for the decomposition products analyzed.
