A labeled diagram of the periodic table entry for boron shows its atomic number 5, symbol B, electron configuration, atomic weight range, and classification as a solid, weakly acidic, other nonmetal with a rhombohedral crystal structure at room temperature. — boron Properties of boron.

Both boron-10 and boron-11 possess nuclear spin—with values of 3 and 3/2, respectively—which makes them useful in nuclear magnetic resonance spectroscopy.

Because of these properties, the isotopes are utilized in the following ways:

Direct Detection: Spectrometers specifically adapted to detect the boron-11 nucleus are commercially available for analysis.1
Resonance Splitting: Both boron-10 and boron-11 nuclei cause splitting in the resonance spectra of other nuclei, such as hydrogen atoms bonded to boron. This results in the appearance of new bands in the resonance spectra, providing structural information about the molecules being studied.1
