Abstract: In this paper, three topological indices Am1, Am2 and Am3 have been applied to multivariate analysis in structure property relationship studies. The topological indices of fourtythree asymmetrical phosphono bisazo derivatives of chromotropic acid have been calculated. The structure-property relationship between color reagents and contrast of color reactions with cerium has been studied by Am indices and structure selective factors. Good results have been obtained.
