Abstract
A pool of distance-based topological indices has been used for the estimation of 1 3 C NMR shifts in benzene derivatives. The regression analysis of the data has shown that Wiener (W)-. Szeged (Sz)-, PI (Padmakar-Ivan)- and first-order molecular connectivity ( 1 Χ)- indices gave more or less similar results, 1 Χ gave slightly better results. The use of other indices were less significant.
