Nuclear quadrupole resonance by Fourier transform of the free induction decay

Nuclear Quadrupole Resonance by Fourier Transform of the Free Induction

Fourier Transform spectrometry has been applied to nuclear quadrupole resonance (NQR). This increases the sensitivity and avoids the creation of side-bands produced by the usual superregenerative spectrometer. It provides also the possibility of determining the true spectral line-width and studying the fine structure of NQR spectral lines.

Fourier Transform Multiple Quantum Nuclear Magnetic Resonance

The excitation and detection of multiple quantum transitions in systems of coupled spins offers, among other advantages, an increase in resolution over single quantum n.m.r. since the number of lines decreases as the order of the transition increases. This paper reviews the motivation for detecting multiple quantum transitions by a Fourier transform experiment and describes an experimental appr...

Nuclear Quadrupole Resonance*

A resonance phenomenon which is closely related to NMR is nuclear quadrupole resonance (NQR), which was discovered in 1950 by Dehmelt and Kruger. All nuclei with a spin > 1 possess in addition to the magnetic moment, an electric quadrupole moment eQ, which measures the deviation of the distribution of the positive charge in the nucleus from spherical symmetry. While e is the elementary charge, ...
