Oxygen-17 Nuclear Magnet Resonance (17O NMR) is one of the very few methods that can verify molecular size. The ordinary tap water’s 17O NMR of half-width is greater than 130Hz which is composed of large molecular units (between 12 and 20 individual H2O units). While water’s NMR half-width less than 90Hz can be called “small molecules cluster water”. By using HKE hexagonal water generator, the result of NMR half-width test is less than 70Hz (defined as long-acting hexagonal water or small molecule water), which is shown to normally average just 6 molecules per cluster.
