Whereas JAB involves the nuclear magnetogyric ratios, the reduced coupling constant KAB represents only the electronic contribution and is thus approximately isotope independent and may exhibit chemical trends. [Pg.25]

The desire of physicists to measure precisely nuclear magnetogyric ratios was, as we have seen, one of the impelling [Pg.382]

Ti[ = transverse relaxation time of free state 13 = Bohr magneton Vn = nuclear magnetogyric ratio 5 = induced shift [Pg.483]

Because J arises from the magnetic interactions of nuclei, the simplest factor affecting it is the product yjY of the two nuclear magnetogyric ratios involved. For example, in FI F is 82 FIz, i.e. x yo/yf - This totally predictable factor is sometimes discounted by quoting the reduced coupling constant = [Pg.1452]
