Magnetic shielding surface in molecules. Neutron as a probe in the hypothetical magnetic resonance spectroscopy.

by Wolinski, Krzysztof

It is proposed to analyze the magnetic shielding tensor as a continuous function of space point coordinates in atoms and molecules. Such a three-dimensional magnetic shielding surface should be very helpful for better understanding of nuclear magnetic shieldings, which is not a trivial problem. The magnetic shielding surface provides more information about molecular electronic structure than nuclear magnetic shieldings alone. A connection between magnetic shielding at an arbitrary point and nuclear magnetic shielding can be made by ''performing'' a hypothetical NMR experiment using a neutron as a virtual probe, instead of nuclei with nonzero magnetic moments. The theory is illustrated by the numerical results of the magnetic shielding surface calculations for atoms and small linear molecules.
