Application of Characteristics Parameters to Studying High Tc Superconductors

The calculation method of molecular average electronegativity (\barX _MO), ionization potential of metal ions for per oxygen atom (Σ_IM), and partial charge of atoms(δ_O,δ_M)has been proposed.As an illustration of the proposed parameters to study superconductors, the author has investigated the change low of T_c of YBCO,YBSCO,BiSCCO,TIBCCO,TIRECCO,TIRESCCO and RBSCO serieses.The results were found to be Fig.1 to 5.
