Fr. Burden, A CHEMICALLY INTUITIVE MOLECULAR INDEX BASED ON THE EIGENVALUES OF A MODIFIED ADJACENCY MATRIX, Quantitative structure-activity relationships, 16(4), 1997, pp. 309-314
A new molecular index is proposed that is derived from the eigenvalues
of a modified adjacency matrix. The construction of the matrix is che
mically intuitive in that its elements relate to atomic and bonding pr
operties. The index was tested by comparing its performance in predict
ing the experimental LogP of 230 compounds. The predictive power of th
e index is shown to be both superior than and complementary to traditi
onal connectivity indices, chi, for LogP.
