NMR of non-interacting spins

In the high-temperature limit, the thermal equilibrium density operator for a system of nuclei under action of a static magnetic field is therefore given by  [Pg.47]

The matrix representations of the nuclear spin operators in the /, wi) basis for the simple [Pg.47]

These matrices are thus directly related to the famous Pauli matrices, largely used in problems involving the spin of the electron [2]. [Pg.47]

From Equation (2.5.14), the deviation density matrix in thermal equilibrium under a [Pg.47]

As described previously, the analysis of the effect of RE pulses is best conducted by using the concept of the rotating frame. The transformation of the density operator from the laboratory to the rotating frame (which rotates around the z-axis with frequency = -72k) is accomplished with the use of the rotation operator [4]  [Pg.47]
