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 multip

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
## Abstract Lactate is an important metabolite in normal and malignant tissues detectable by NMR spectroscopy; however, it has been difficult to clinically detect the lactate methyl resonance because it is obscured by lipid resonances. The selective homonuclear multiple quantum coherence transfer t
