| Abstract: | The molecular connectivity indices of twenty nine asymmetrical phosphosphono bisazo derivatives of chromotropic acid have been calculated. The relationship between structure of color reagents and mp-lar absorptivities of their color reactions with cerium has been studied in detail by molecular connectivity indices and structure selective factors. Good results have been obtained by using correlation equation,and the molar absorptivities of new color reagents are predicted. |
