Applications of Nuclear Quadrupole Double Resonance Spectroscopy
Nuclear Quadrupole Resonance (NQR) spectroscopy measures the interaction of a nucleus possessing an electric quadrupole moment Q with the electric field gradient (efg) produced at the nucleus by its local electronic environment. As a result, the NQR technique provides information on the ground …

Development of a Laminar Construction Quadrupole Ion Trap
The three-dimensional quadrupole ion trap (QIT) is an extraordinary device. It functions both as an ion store in which gaseous ions can be confined for a period of time and as a mass spectrometer of considerable mass range and variable mass resolution. Over the past few decades, it has evolved into …
