This contribution concerns
itself with the HR PMR measurements in single crystalline solids, by which the
chemical shift tensor of protons in organic molecules would be determined. In
these series of experiments, after the elaborate acquisition of data followed by
analysis, invariably, a situation would result in which the analyzed data do not
reflect the requirements according to the molecular symmetry for the orientation
of the principal directions of the chemical shift tensor. These conflicting
results could not be reconciled until a simple approach to try to account for
the intermolecular contributions to the shielding could be envisaged, based on
the experiences in the HR PMR in liquid state. This approach was the well
evidenced neighbor group contributions to isotropic chemical shifts calculable
in several contexts satisfactorily using the magnetic susceptibility anisotropy
of the neighbor groups. Samples of spherical shape were used for making the
measurements because of which the bulk susceptibility contributions to chemical
shift were ensured to be zero. The contributions from the neighboring molecules
within the Lorentz sphere had to be calculated and subtracted from the
experimentally measured chemical shift values to result in a Tensor that
reflected the intramolecular symmetry. These results [1] first established in
1979 has subsequently triggered a cascaded effort. Investigations as to whether
this kind of neighbor contribution can be dependent upon the shape of the
hypothetical boundary around the specified proton site. A spherical enclosure,
the Lorentz sphere, in these contexts is conventionally known; but, ellipsoidal
enclosure around the specified proton is never found to be mentioned. An
argument seems possible that, as much as within a spherically shaped specimen
the bulk susceptibility contribution is zero, within an ellipsoidal shape for
the specimen a hypothetical ellipsoidal semi micro cavity can be carved out
around the proton site for which the induced fields can be zero at the proton
site. These subject matters seem to evoke the interest of specialists in
condensed matter physics with regard to the induced field patterns within
magnetized (magnetic) materials [2]. These consequences have simplifying
features in such a way as to appeal to chemists [3] as well. This perspective
would be explained in this contribution.
