A Newly Proposed Topological Index YM and its Application in Correlationwith Optical Basicities Scale of Binary Oxides

This paper proposes a new topological index Y M. The Y M of binary oxides MO m /2 molecules are calculated. The linear least square regression shows that correletion between Y M and the optical basicities of some binary oxides is excellent. Through calculation of optical basicities of 110 homologous chemical compounds, it shows that the results of calculation are in accordance with experimental results. The method also applies to the binary oxides of subgroup elements.
