Abstract:
Using the valence electron orb it energy (E i ) and number of valence electron shell (ni ), a new connectiv ity topo logica l index ( m V) w as proposed from Di. The 0 and 1 order indexes of m V were corre lated w ith lattice energy, entha lpy of format ion and hydrated energy of 20 k inds of alkali ha lides, and w ithmelting poin,t magnet ic susceptib ility and bond length of 16 kinds o f alkali halides. Some regression euqations w ere suggested, the ir related coefficient r ( re-re lated coefficient R ) d ifferent is 01996 0 ( 0.996 2), 0.982 2 ( 0.982 4), 0.978 7 ( 0.978 7), 0.952 6, - 0.990 9 and - 0.993 3. The resu lts show that the proposed indexesw ith fairly high and extensive correlation ability are useful parameters in QSPR and QSAR research o f inorganic compounds.
