A pulse sequence for localized in vivo (1)H NMR spectroscopy is presented, which selectively filters single-quantum coherence built up by strongly coupled spin systems. Uncoupled and weakly coupled spin systems do not contribute to the signal output. Analytical calculations using a product operator

This is Part II of a short introduction to multipulse NMR. On the basis of the results ( ) obtained in Part I Concepts Magn. Reson., 1996, 8, 17α32 for single-spin systems, the product 1 operator formalism for the weakly coupled two-spin-system is described. The equilibrium, 2 pulse effect, and the
In this article, we consider the evolution of weakly coupled I m S n systems of spin-1 2 nuclei during arbitrary RF irradiation of the I spins. Exact solutions are presented for the time dependence of the density operator in terms of its constituent product operator components for a complete set of
