ABSTRACT
We report here evidence for the generation of 7Li multiple-quantum coherences in aqueous solutions outside of regimes where conventional multiple-quantum coherences due to alignment or quadrupolar relaxation could be observed. These coherences are shown to observe nonlinear behavior as a function of concentration, and hence these effects can be identified as arising from intermolecular multiple-quantum coherences. Due to the importance of lithium ion solutions for the study of electrochemical systems, awareness of such coherences is particularly important in the interpretation of experimental results, and new applications using lithium as a probe may become possible on this basis.
