The general connectivity index R α (G) of a graph G=(V, E) is defined as R α (G)=∑(u, v)∈ E (G)(d u d v) α, where (u, v) is an edge of G, d u and d v denote the degrees of the vertices u and v, respectively, and α≠ 0 is an arbitrary real number. In this paper, we give the expressions for computing the general connectivity indices of fluoranthene-type benzenoid systems, and we determine the extremal values of R α (G) in f-benzenoid systems with h hexagons for some real number α. Especially, the extremal values of R α (G) in cata-catacondensed fluoranthene-type benzenoid systems with h hexagons were studied.
