2023年3月30日 · Nuclear Quadrupole Resonance (NQR) or Zero-Field Nuclear Magnetic Resonance (NMR) is used to detect atoms whose nuclei have a nuclear quadrupolar moment. …

We can also show that for I = 3/2, only two levels (one NQR transition) can be observed. NOTE NQR must be done on solid samples, for molecular tumbling in liquids averages field gradients …

This chapter presents nuclear quadrupole resonance data in graph form. There are numerous reports of the resonance frequencies in the literature in the graph form only.

Nuclear quadrupole resonance spectroscopy or NQR is a chemical analysis technique related to nuclear magnetic resonance (NMR). Unlike NMR, NQR transitions of nuclei can be detected in …

2020年11月1日 · Nuclear quadrupole resonance (NQR) represents a solid-state radio frequency (RF) technique used in chemical analysis that was first observed in 1949, by H. Dehmelt and …

2021年10月12日 · The identification of the NQR response signal is a binary classification problem (detected/not detected) and this study aims to propose new signal analysis solutions in order …

Advances in the development of pulse methods for accurate measurement of the field constants of NQR frequencies, 0v/OE z, [1-3] have revealed their highly specific response [4, 5] to the …

• Nuclear quadrupole resonance (NQR) uses radio-frequency (RF) magnetic fields to induce and detect transitions between sublevels of a nuclear ground state. • Nuclei carrying NQR are able …

Nuclear Quadrupole Resonance (NQR) with its ability of identification specific molecules in measured sample is potentially powerful method in solid state physics, chemistry and …
