Nuclear magnetic resonance flip-angle effects observability of multipole operators. II

General FTNMR sampling-pulse flip-angle dependencies of non diagonal multipole operators are derived and discussed. It is demonstrated that the efficiency of the polarization transferred between the multipole operator, [math], and the implicit observable [math] is uniquely related to the chosen flip-angle. The angle dependent efifciencies of other polarisation transfers are also considered. The formalism developed in this work is valid for spin systems of arbitrary dimension and character
