The nuclear magnetic resonance (NMR) spectrum of sodium was determined in muscle and erythrocytes using conventional continuous wave techniques. NMR spectra of fresh intact muscle revealed a single line with a width of about 38 Hz equivalent in intensity to about 53% of the total muscle sodium, in general agreement with previous work. Prolonged washing with sodium-free solutions led to a marked loss of both total and NMR-detectable sodium. The NMR-visible sodium remaining in the muscle was somewhat larger than the fraction calculated to remain extracellular and, presumably, was intracellular. The original sodium signal is thus interpreted as arising from both extracellular sodium and the narrow line portion of the signal from intracellular ...
