Journal of Mathematical Chemistry Aims and scope Submit manuscript

Given PH a phenylene, and HS its corresponding hexagonal squeeze, their second-order Randić indices are denoted by 2χ(P H) and 2χ(H S), respectively. The expressions of both 2χ(P H) and 2χ(H S) in terms of their inlet features are found, and a simple relation is estabblished between the second order Randić index of a phenylene and of the corresponding hexagonal squeeze.
