In Equation , C Q is the quadrupolar coupling constant of a single atom of 7 Li, which defines the magnitude of the tensor V, ⌘ is the asymmetry parameter which describes the shape of the tensor V, and ✓ and describe the orientation of the tensor V with respect to an external reference system . Using DFT, it is possible to calculate an individual C Q and ! Q for every single Li atom in the simulation. An SAE NMR experiment measures an ensemble average of the single particle correlation functions for each Li atom within different electronic environments, which have distinct ! Q .
