Summary
A method of increasing the strength of nuclear magnetic resonance signals by factors up to 100 or even more is suggested. The principle is to increase the quality factor Q of the coil containing the sample by means of positive feedback. Experiments on proton resonance in water, treated with ferric nitrate solution, using a Q-multiplier with the amplitude bridge, are described.
