Abstract: Systematic studies were made on 13C NMR and its regularity of chemical shift sum (CSS). In this paper, a set of novel molecular graph-theoretical parameters, called the distance-edge vector (lambt,λ) was developed and found to be excellent correlated with 13C NMR CSS of alkanes as
CSS=-24.2937+32.1835λ1+24.8344λ2+24.4614λ3+25.9988λ4+15.2348λ5+0.4016λ6+23.8872-λ7+38.9112λ8+78.3879λ9+146.0000λ10
which gave good results.
