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.
متن کاملThe Rotational Spectra of Fluorinated Acetonitriles; N-nuclear Quadrupole Hyperfine Structures Measured with a Microwave Fourier Transform Spectrometer
The microwave spectra of CF3CN, CH2FCN, CHDFCN, CD2FCN and CHF2CN have been measured and analysed. The nuclear quadrupole hyperfine splittings due to N have been measured by Microwave Fourier Transform spectroscopy. The nuclear quadrupole coupling constants, transformed to the bonding axis systems of the C C = N groups, are shown to be in accord with structural predictions of the p-electron pop...
متن کاملNitrogen-14 NQR in s-Triazine Derivatives*
Within a study of the temperature dependence of NQR frequencies in some s-triazine derivatives [1], resonance frequencies at 4.2 K were determined in melamine, cyanuric acid, and cyanuric chloride. New lines, which were not reported so far, were detected in two of these compounds. In melamine, nine more lines were found as already described in [4], In cyanuric chloride, two more lines were foun...
متن کاملLow Frequency Nuclear Quadrupole Resonance with SQUID Amplifiers*
The dc SQ U ID (Superconducting QUantum Interference Device) can be configured as an ampli fier of spin-echos with a noise temperature of approximately 10 mK (f/1 MHz) at an operating temperature of 1.5 K. A Fourier transform spectrometer based on a SQ U ID with a superconducting input circuit and operated in a flux-locked loop is used to obtain nuclear quadrupole resonance (NQR) spectra in a ...
متن کاملNatural-abundance Carbon-13 Fourier Transform Nmr Studies of Large Molecules
The resolution in proton-decoupled natural-abundance i3 NMRt spectra of large organic and biological molecules is normally considerably greater than in proton NMR spectra, as a result of the large range of '3C chemical shifts 'and the absence of' 3C—' 3C coupling. The Fourier transform NMR technique has partly overcome the problem of very poor sensitivity of natural-abundance l3 NMR. As example...
