Compilation until 1979 of the literature on 15N parameters, namely chemical shifts and coupling constants, has provided a large amount of data. Examination of Fig. 1.1 shows that most 15N resonances lie in a 500 ppm range, although some compounds, such as nitroso derivatives, extend the field of δ 15N to 800 ppm.

Abstract Graph theoretical schemes have been found useful in systematic searches for regularities in available molecular data. In particular, enumeration of paths of different lengths provides a basis for characterization of atomic environments in a molecule as well as the molecule as a whole.

The chemical shift (as defined by IUPAC) in terms of measured frequencies $$ \delta = \left( {\nu - \nu _{{\text{ref}}} } \right){\text{/}}\nu _{{\text{ref}}} $$ (1) is related to a fundamental molecular property, the nuclear magnetic shielding, σ.
