Frédéric Perras and Wenyu Huang, scientists at Ames National Laboratory, and colleagues have used advanced 11B NMR experiments as well as powder diffraction data to investigate the structure of boron monoxide. The team found that there were two resonances in 11B MAS solid-state NMR spectra, one of which they assigned to BO. The other appeared at synthesis temperatures of 300 °C and above. It was assigned to B2O3, which forms a separate phase from BO.
The research is published in the Journal of the American Chemical Society, 'The Structure of Boron Monoxide.'
