C. Akay et A. Yalciner, A NEW WEAK-FIELD DOUBLE-RESONANCE NMR SPECTROMETER, Zeitschrift fur Naturforschung. A, A journal of physical sciences, 50(2-3), 1995, pp. 177-185
Weak field NMR and double resonance spectrometers are mostly homemade.
In this work, some electronic units of such a spectrometer operating
at 1.437 mT were designed and realized by including new integrated cir
cuits: an audio generator, digital sweep generator, digital additional
field and delay unit, Quartz generator, NMR detector(Q-meter), AF-nar
rowband amplifier, phase shifter and phase sensitive detector.
