WebFeb 28, 2015 · Chemical Shift Anisotropy (CSA). The chemical shift of a nucleus is a function of the orientation of the molecule in the magnetic field (i.e. it is a tensor quantity), provided the nucleus is... WebDepending on the local symmetry at the nuclear site, the magnitude of the chemical shift will vary as a function of the orientation of the molecule with respect to the external magnetic field. This orientation dependence of the chemical shift is referred to as chemical shift anisotropy (CSA).
