Abstract
A versatile multichannel multifrequency pulse nuclear magnetic resonance (NMR) spectrometer constructed for use at Los Alamos Scientific Laboratory is described. The spectrometer operates on the frequencies 8, 15, and 30 MHz, and the nf transmitter can be readily modified to opemte at 16, 24, 32, 45, 48, 60, 90, or 120 MHz. Details of the opemtion of the instrunnent, including circuit interconnections for most common pulse NMR experiments, is presented. Complete circuit diagrams are also included, as well as a discussion of a number of possible future modifications to the instrament. (auth)
