Abstract

A simple and useful disentangling technique of the propagator, known as the rotation operator approach, is applied to weakly scalar-coupled spin-1/2 systems where a given spin or group of magnetically equivalent spins alone is irradiated by a shaped selective pulse. The theory employs the product operator base as well as the single-transition operator base. The treatment of a two-spin system is given in some detail, and that of larger spin systems given in outline. It is shown that the three Euler angles for a given shaped RF pulse are very concise and exact, and are readily applicable to the case of coupled spin systems.
