Intracellular water volume is an important pararreter for expressing corcentration of intracell ular ions and diffusional water of rreabiby of cells by nuclear magnetic resonarce (NMR). Presented here, is a method using 35CI and deuterium (2D) NMR spectra of cell-free supernatant and cell suspension to get intracellui ar water volurre. The vol of intracell cell water as a fraction of the total cell volurre, Vi/Vc-in isosmotic solution is 0. 706 0.065.
