The Inorganic Oxygen Acids and the Molecular Topogical Index
Zhao Xu-sheng · Journal of Qinghai Junior Teachers' College · 2006
A new molecular topological index (Y=((δ_R+h)(m+k~(0.25(m+1))))/(δ_R~(0.5)+n~(0.5))) is defined in this paper.The linear equation between the new molecular topological index and 27 kinds of pKa_((1)) inorganic oxy-acids is Pka_1=11.190-0.429δ_R+1.168n-2.914Y,R=0.986.It is concluded that the new molecular topological index has good structure selectivity property relativity and it can calculate the numerical value of other pKa_((1)) inorganic oxy-acids.
