A very widely known and widely used[1]expression to calculate a nuclear magnetic shielding constant by combining the effect of diamagnetic and paramagnetic atomic currents on each atom was given by Pople.[2,3]In the present article, we will present a remark on a restriction to the applicablity of Pople's induced current theory.[2,3]To simplify the discussion, we will deal with a simple hydride MH, in which paramagnetic circulation can occur only in the atom M. The rectangular coordinates x, y and z are taken as Fig. 1.
