The results indicate that the heteropolyanion VMo12O403-undergoes three reversible one electron transfer reductions and the mixed-valenceheteropolyanion VMo12O40n-(where n=4,5,6) was formed after electroreduction. The spectraof the aforementioned mixed-valence compounds were characterized by in-situspectroelectrochemical mathods展开更多
The redox behaviours of a donor-acceptor model compound. p-tricyano-ethenyl-N, N-dimethyl aniline was investigated by electrochemical and spectroelectrochemical methods.
