Abstract:
Objective To study the characteristic cluster structure of good-quality natural drinking water.Methods The coupling 17 O NMR(nuclear magnetic resonance)FWHM(full width half maximum)was selected as the index to weigh the rel-ative average size of water cluster in liquid water.The 17 O NMR FWHM of water samples(nature water and artificial water)were measured by ARX400NMR spectroscopy.Results 17 O NMR FWHMs of21representative water samples were in the range of53-145Hz.Conclusion 17 O NMR FWHM of good-quality natural drinking water mainly lay from70to90Hz.
