Nuclear magnetic resonance (NMR) has been used for some 40 years to study atomic arrangements, chemical bonding, and structural groupings in borate glasses and crystalline compounds, and nuclear quadrupole resonance (NQR) has more recently increased

Pure nuclear quadrupole resonance (NQR) spectroscopy at low frequencies (down to 275 kHz) has been used to investigate a number of borate, aluminate, and vanadate crystalline compounds and borate glasses. The values of the quadrupole coupling constan

Pure nuclear quadrupole resonance (NQR) studies of 10B and 11B in borate glasses have been accomplished. The data yield values of the quadrupolar parameters (the coupling constant Qcc and the asymmetry parameter ν) that are an order of magnitude mor

Pulsed nuclear-quadrupole-resonance (NQR) measurements have been performed on rhombohedral, orthorhombic, and amorphous (a − ) arsenic. Measurements of T 1 provide evidence of low-frequency disorder modes in a-As. The NQR frequencies indicate that

Pulsed nuclear quadrupole resonance (NQR) experiments have been performed on three forms of elemental arsenic: amorphous (a), rhombohedral (rh), and orthorhombic (or). The temperature dependence of the spin-lattice relaxation time (T/sub 1/) provides
