✦ Synopsis
An acyclic glycol ether ligand with two nitroxide groups shows in frozen solution a dipole-dipole interaction only in the presence of potassnun ions. Al TOOT temperature the spin-spin exchange is still observed, but it is amplified in presence of K+, The results UC discussed in terms af conformational effects that mimic allosteric effects.Synthetic models which mimic allosteric effects have been described (1) by some authors.
