Abstract

Recently proposed Cluj matrices: the C1uj-distance matrix and the Cluj-detour matrix are reviewed. New Harary-type indices on the detour and Cluj-detour matrices are defined. Additionally, the formulae for calculating these induces of cycles are derived. Modelings of boiling points for a set of 32 acyclic and cyclic octanes using Cluj indices and their Harary counterparts is presented. The best structure-boiling point relationships are obtained by means of the multiple linear regression using either combinations of two reciprocal paths numbers (1/p(2), 1/p(3)) and detour and hyper-detour indices or a combination of the same two reciprocal path numbers and Harary indices derived from the edge-defined and path-defined Cluj matrices.
