We report on electron paramagnetic resonance (EPR) and B11 nuclear magnetic resonance (NMR) study of multiwall boron nitride nanotubes. We measured the whole B11 NMR spectrum in the external magnetic field of 8.0196T and the central 12→-12 transition in 1.22T. The quadrupole coupling constant and asymmetry parameter were determined from the splitting between satellites and by analysis of the line shape of the central transition. We show the closeness of these parameters in boron nitride nanotubes and bulk hexagonal BN. The spectra correspond to the axial symmetry of the boron site. EPR and x-ray photoelectron spectra are comparable to those of powder BN. The data obtained reflect a very similar local symmetry of the boron site and charge distribution over the BN bond in nanotubes and bulk BN. These facts explain why BN nanotubes hold the electronic properties of the bulk compound.
