  • Insulation and Molecular Properties of Alternative Gases

    In this study, SF6 and its alternatives (tetrafluoromethane (CF4), methane (CH4) and carbon dioxide (CO 2)) are investigated with regard to insulation and molecular properties by calculating the distribution of electrostatic potentials using Gaussian 09 and Gauss View 5.0 molecular software programs. The molecular orbital values (homo and lumo), energy gap, hardness, electronegativity, total energy and molecular volume of each gas are obtained by this analysis.
