Abstract
Studies have been made of the proton magnetic resonances of ethyl alcohol under considerably higher resolution than has heretofore been reported. A description of the apparatus includes details of construction of a large permanent magnet, with some of the considerations directed toward improvement of resolution by reduction of field inhomogeneities. Also, the features of a specially designed nuclear magnetic resonance head are described. This head is provided with facilities for spinning the sample for the further reduction of the effective field inhomogeneity. Considerations of stability of the field and the radio-frequency components are briefly discussed.
