Room-temperature 51V solid-state MAS NMR spectra of the starting materials and the products of their thermal transformations (ppm = parts per million). a compound 2, b compound 3-Zn. The temperatures given correspond to the maximum heating temperature. The asterisks indicate spinning sidebands. The signals attributed to β-BiVO4 are indicated by arrows, which indicate the possible positions of the isotropic resonance and a spinning sideband. While β-BiVO4 is expected to contain only one distinct V site, the large linewidth makes the identification of the isotropic peak challenging.
