Correlations: Alkylsilane property — polynomial coefficients of the adjacency matrix of the molecular graph

Based on the characteristic polynomial coefficients (CPCs) of the adjacency matrix A′ of heterogeneous molecular graphs of the molecules containing a tetravalent heteroatom >Si< (>Ge<, >Sn<), etc. in the chain, a 13-constant additive scheme for the calculation of their physicochemical properties is obtained. The structural meaning of CPCs of the adjacency matrix A′ is established. By the formula obtained the formation enthalpies ΔfHgas, 298K0 of SiCnH2n+2 alkylsilanes not studied experimentally are calculated.
