## Abstract The evaluation of the characteristic polynomial of a chemical graph is considered. It is shown that the operation count of the Le Verrier–Faddeev–Frame method, which is presently considered to be the most efficient method for the calculation of the characteristic polynomial, is of the o
## Abstract Kekulé structures of 10 nonlinear acenes comprising 83 graphs are studied through the use of connectivities [M. Randić, J. Am. Chem. Soc. **97**, 6609 (1975)] of their corresponding submolecules [H. Joela, Theor. Chim. Acta **39**, 241 (1975)]. In certain rare cases states were identifi
