23Na intermolecular multiple-quantum coherences in salt solutions
The phenomenon of intermolecular multiple-quantum coherences (iMQCs) has been known for decades, mainly for spin-1/2 nuclei. However, the iMQC of 23Na, a spin-3/2 quadrupolar nucleus, has not been studied previously. In this communication, we report the observation of 23Na iMQC signals arising from 23Na–23Na long-range dipolar interaction in the aqueous solutions of various sodium salts. We investigated the iMQC signal in response to different experimental parameters. We also formulated a theoretical model to explain the experimental results. Since sodium ions play important roles in biology and industry, 23Na iMQC experiments could bring new insights into ion dynamics and interactions in solutions.
