Degeneracy in cryptophane-xenon complex formation in aqueous solution

The reversible binding of xenon to cryptophane molecules is currently heavily explored for application as a reporter system in NMR. Herein, for aqueous solution, first evidence of degenerate exchange in this host-guest system is presented based on a novel approach using hyperpolarized (129)Xe.
