- Аннотация: Ratio of H2O ortho-/para-spin-isomers in water of different treatment procedures (distilled or cavitation fountain) were studied by both Rayleigh wing four-photon spectroscopy and 1H nuclear magnetic resonance (NMR) spectroscopy. Low-frequency gas-like rotational resonances were observed in the 0.1–1.5 cm–1(3–45 GHz) spectral range and NMR proton density was measured in both water samples. We established thatthe intensity of ortho-isomer line (616–523) 0.74 cm–1 measured by four-photon spectroscopy increases by factorof ~3.5 after cavitation treatment of distilled water. Moreover, the proton density measured by NMR spectroscopy in the same sample grows on ~17%. We have suggested that the enrichment of the distilled water byortho-H2O molecules was achieved due to cavitation bubbles collapse when the water passes through the supercritical state.PACS numbers: 78.47.Fg, 78.47.Nj, 76.60.PcDOI: 10.1134/S1054660X09030104
