Amplitude Modulation Method for Producing Sidebands in NMR Experiments

Louis G. Alexakos, C. D. Cornwell

Open publisher page 8 citations

Abstract

The use of amplitude modulation for the generation of sidebands offers certain advantages in NMR experiments, particularly when relatively large modulation frequencies (say above 1 kc) are required. For the Varian 40- and 60-Mc high resolution spectrometers, minor circuit modifications are described by means of which usable sideband signals are produced for modulation frequencies up to 70 kc, with amplitude reasonably constant from 200 cps to 40 kc.
