The exchange reaction between M+PQ−• ion-pairs and MeHgCl leads to the formation of MeHgPQ• adduct with a characteristic low g-factor of 2.00052 and a small methyl proton splittings of 0.16 G. The dynamic and equilibrium aspects of the exchange depend upon the alkali cation, the concentration of MeHgCl, and for M+PQ−• also on temperature. The MeHgPQ• is found to be relatively stable at room temperature and in the presence of water. These results may be of potential value to toxicology studies of methylmercury.

Spin Resonance Study

We report the first direct experimental evidence of the presence of antiferromagnetic dimers in VOx nanotubes based on the high frequency (60 GHz) electron spin resonance study carried out in the temperature range of 4.2-200 K. Arguments favouring a possible observation of the low temperature quantum critical phenomena in VOx nanotubes are provided.
