Sauer et al. [185] determined the gyromagnetic ratio g(9/2)/g(7/2) and the magnetic moment of the 6.2 keV level in Ta in two ways, (1) from the Zeeman split velocity spectrum of a metal source in a longitudinal field versus a Ta [Pg.298]

Nuclide Spin I Electric quadmpole moment eQ (10-2 m2) Natural abundance (%) Relative sensitivity Gyromagnetic ratio y (103 radT- S-l)a NMR frequency (MHz) Bo = 2.3488 T)3 [Pg.87]

By multiplying eq. (1.18) with the gyromagnetic ratio y one obtains the time dependence of the magnetic moment ft, remembering that fi = yp [Pg.9]

The proportionahty constant y is called the gyromagnetic ratio which is a function of the magnitude of the nuclear magnetic moment. Therefore each isotope having a net nuclear spia possesses a unique y. The y of some biologically relevant nuclei can be found ia Table 3. [Pg.53]

This nuclear magnetic moment fl is represented by a vector that is colinear to I and has the same or opposite direction depending on the sign of 7, the gyromagnetic ratio (also called the gyromagnetic constant). [Pg.129]

It is traditional to rewrite the definition of the nuclear magnetic moment in terms of magnetons and include a constant of proportionality called the gyromagnetic ratio or simply g factor [Pg.49]

The following table lists the gyromagnetic ratio, y, of some important nuclei that are probed in NMR spectroscopy.1-12 The gyromagnetic ratio is the proportionality constant that correlates the magnetic moment (p) and the angular momentum, p p = yp. [Pg.408]

S is the sum of the spin quantum numbers, to which each electron contributes /2 and g is the gyromagnetic ratio, i. e. the ratio of the magnetic moment to the angular momentum. For a free electron, g = 2. [Pg.119]

The angular momentum L has associated with it a magnetic moment /z. Both are vector quantities and they are proportional to each other. The proportionality factor y is a constant for each nuclide (i.e. each isotope of each element) and is called the gyromagnetic ratio, or sometimes the magnetogyric ratio. The detection sensitivity of a nuclide in the NMR experiment depends on y nuclides with a large value of y are said to be sensitive (i.e. easy to observe), while those with a small y are said to be insensitive.
