SPECTROSCOPY 7.89
7.7 NUCLEAR MAGNETIC RESONANCE
TABLE 7.41
Nuclear Properties of the Elements
In the following table the magnetic moment is in multiples of the nuclear magneton N (eh/4Mc) with
diamagnetic correction. The spin I is in multiples of h/2, and the electric quadrupole moment Q is in multiples
of 10 28 square meters. Nuclei with spin 1
⁄2 have no quadrupole moment. Sensitivity is for equal numbers of
nuclei at constant field. NMR frequency at any magnetic field is the entry for column 5 multiplied by the value
of the magnetic field in kilogauss. For example, in a magnetic field of 23.490 kG, protons will process at 4.2576
23.490 kG 100.0 MHz. Radionuclides are denoted with an asterisk.
The data were extracted from M. Lederer and V. S. Shirley, Table of Isotopes, 7th ed., Wiley-Interscience,
New York, 1978; A. H. Wapstra and G. Audi, “The 1983 Atomic Mass Evaluation,” Nucl. Phys. A432:1–54
(1985); V. S. Shirley, ed., Table of Radioactive Isotopes, 8th ed., Wiley-Interscience, New York, 1986; and
