## Abstract To quantify metabolite and cation concentrations using NMR spectroscopy, the volumes of intracellular and extracellular spaces must be known. We describe a simple ^31^P NMR spectroscopic method that employs dimethyl methylphosphonate (DMMP) as a marker of total water space and phenylpho
We have used a combination of a shift reagent and mathematical filtering or presaturation of the extracellular sodium resonance for the quantitative investigation of the intracellular sodium and lithium relaxation times in the perfused frog heart. While the TI of the intracellular sodium was found t
