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).

WebBoth isotropic and anisotropic chemical shifts of C2 are substantially higher than those of the C8 nuclei. The presence of “nucleophilic suction pumps” creates a deshielding effect … WebFurthermore, 15 N chemical shift anisotropy (CSA) suggested that Ser112 and Ser234 polar residues distinguish the electronic environment tendencies of RPSB from those of other microbial rhodopsins. Our NMR results revealed that the retinal chromophore and the RPSB in TaHeR exhibit unique electronic environments.
