Determination of Electronic Structure of Molecules from Nuclear Quadrupole Effects
TL;DR: In this article, it was shown that this variation of electric field is usually simply related to the molecular electronic structure, being primarily dependent on the way in which valence electrons fill the lowest energy p-type orbits.
