Nuclear Quadrupole Resonance of Pentaerythritol Tetranitrate (PETN) in Different Compositions

摘要

Pulsed NQR signals from the ~(14)N 495 kHz v_- spectral line of pentaery-thritol tetranitrate (PETN) for the two PETN containing high explosives, Semtex H and Detasheet are compared with those observed from a commercial sample of 20 % PETN/Lactose as used in vasodilator drugs. The results show that the latter has a narrower spectral line and a longer T_(2e) decay time for PSL multiple echo trains.
