โฆ Synopsis
The creation of multiple-quantum coherences is not forbidden in experiments that employ a single non-selective radiofrequency pulse of arbitrary flip angle. In addition, such a pulse does not forbid coherence transfer between any two coherences. The role of population distribution in creating multiple-quantum coherences for equilibrium is discussed.

Multiple quantum coherences are created by a single nonselective pulse from the equilibrium density matrix when the high-field approximation breaks down. In this situation the equilibrium density matrix also contains bilinear spin operators. In the case of a two spin system having scalar as well as
