Prediction of Molar Absorptivities of color Reagents and Their Color Reactions with Yttrium by Artificial Neural Networks

摘要

The new topological indices Ax1-Ax3 suggested in our laboratories were applied to the study of structure- property relationships between color reagents and their color reactions with yttrium. The topological indices of twen- ty asymmetrical phosphone bisazo derivatives of chromotropic acid were calculated.
