Systematic studies were made on carbon-13 nuclear magnetic resonance (13C NMR) and its regularity of chemical shift (CS). In the present paper, A novel atomic distance-edge (ADE) vector or ν vector expressed in the form of energy was developed and found to be correlated excellently with the chemical shift (CSC) for carbon-13 nuclear magnetic resonance (13C NMR). The multiple linear regression (MLR) equations, CSC=aν+ap\-3=∑m\-j=0a\-jν\-j+a\-10p\-3=a\-0(ν\-0=1)+a\-1ν\-1+a\-2ν\-2+a\-3ν\-3+a\-4ν\-4+bP\-3., of atomic modelling were established by the atomic distance-edge vector together with the path count of three bonding segment (C-C-C) It gives very good results for the modelled estimation and quantitative prediction with cross validation (CV) of leave-one-out (LOO) procedure.
A reliable correlation model has been developed by using the combination of ADE vector (ν vector) and atomic path counts of length three (P\-3), as adjoin structural descriptors.
