In thi paper, three topological indices, Am1, Am2 and Am3, have been applied to multivariate analysis in structure-property studies. The topological indices of twenty asymmetrical phosphosphono bisazo derivatives of chromotropic acid have been calculated. The structure-property relationships between color reagent and molar absorptivity of color reactions with yttrium have been studies by Am indices and structure selective factors. Good results have been obtained by using correlation equation to predict the molar absorptivity of new color reagents.

Key words: PHOSPHONIC ACID P, COLOUR REAGENTS, COLOR REACTION, YTTRIUM, AZO COMPOUNDS
