Ground and excited state similarity studies by means of Fukui and dual-descriptor matrices

This Letter reports a quantitative study of the similarity between the Fukui matrices corresponding to the ground state and those of the first excited state of a molecular system, as well as between the dual-descriptor matrices of those states. The formulation of the Fukui and dual-descriptor matric...
