A comparative study of the Wiener, Schultz and Szeged indices of cycloalkanes

摘要

In alkanes, the Wiener (W), Schultz (MTI) and Szeged (Sz) topological indices are known to be closely related, being thus equally capable of predicting the physico-chemical properties of these compounds. We have now examined cycloalkanes and found that for them: (a) W, MTI and Sz are linerly correlated, (b) the correlations of W, MTI and Sz with boiling point, molar volume And molar refraction are curvilinear and for all three indices are of nearly equal quality, and (c) W Yields slightly better results than MTI and Sz.
