Density functional theory (DFT) calculations were performed to compute nitrogen-14 and boron-11 nuclear quadrupole resonance (NQR) spectroscopy parameters in the representative model of armchair boron nitride nanotube (BNNT) for the first time. The considered model consisting of 1 nm length of H-capped (5, 5) single-wall BNNT were first allowed to fully relax and then the NQR calculations were ...

ABSTRACT AbstractA Nuclear quadrupole resonance detector has been developed. This detector targets to RDX, a high explosive inside an anti-personnel landmine, buried up to 15 cm deep. This detector works well outside an electromagnetically shielded room. It was also mounted an anti-mine vehicle and remotely controlled mine detection is demonstrated in public.

1 7 0 nuclear quadrupole resonance spectra have been measured in an l v O enriched polycristalline sample of DL-proline with the help of 1 H l v O nuclear quadrupole double resonance technique. The results show the presence of eight chemically inequivalent oxygen sites corresponding to four inequivalent proline molecules in the unit cell. The oxygen sites may be grouped into two sets of four si...
