30 The isotropic shift is equal to the difference between the chemical shift of
a given nucleus and position in the paramagnetic species in question and
the chemical shift of the same locus in an appropriate diamagnetic refer-
ence compound. For this purpose, we employed the chemical shifts of
complex [Y(1)2(NO3)3] (3) as a diamagnetic reference. See for instance:
