Notizen:
The correlation between molecular path numbers and chemical shift sums found previously in smaller alkanes is extended to larger alkanes. Using data on alkanes with 2-31 carbon atoms a satisfactory regression equation (R = 0.999 and S = 7.5 is derived based on a single molecular descriptor. The simple combination of elementary path numbers, M = P0 + P1+P2 - P3, apparently adequately represents both the size of molecules and the molecular shape, i.e. variations in properties among isomers.
