A partial differential equation for pseudocontact shift. [PDF]

open access: yesPhysical Chemistry, Chemical Physics - PCCP, 2014
It is demonstrated that pseudocontact shift (PCS), viewed as a scalar or a tensor field in three dimensions, obeys an elliptic partial differential equation with a source term that depends on the Hessian of the unpaired electron probability density.
