CORRELATIONS: ALKYLSILANE PROPERTY - POLYNOMIAL COEFFICIENTS OF THE ADJACENCY MATRIX OF THE MOLECULAR GRAPH
Based on the characteristic polynomial coefficients (CPCs) of the adjacency matrix <i>A'</i> 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 <i>A'</i> is established. By the formula obtained the formation enthalpies Δ <sub> <i>f</i> </sub>H <sup>0</sup> <sub>gas, 298 K</sub> of SiC <sub> <i>n</i> </sub> H <sub>2 <i>n</i>+2</sub> alkylsilanes not studied experimentally are calculated.
