A simple circuit for cw NMR measurements is discussed. The purpose of this circuit is similar to that of bridge arrangements: The rf at the input of the receiver is compensated by an additional branch within the circuit consisting of a potentiometer and a phase shifter. As shown by theoretical calculations, the sensitivity of the discussed arrangement is higher than similar uncompensated circuits and higher than bridge arrangements as well. The203Tl and205Tl resonances measured with this circuit show signal‐to‐noise ratios comparable to the signal‐to‐noise ratios of the resonances measured with a commercial wide‐line NMR spectrometer.
