1H-NMR spectra of long-lived water clusters. (a) 1H-NMR spectrum of benzene-d6 mixed with a small amount of water (0.57% water volume content in benzene-d6) at 298 K. (b) 1H-NMR spectrum of water in benzene-d6 kept at 343 K. (c) 1H-NMR spectrum of water in benzene-d6 solution cooled to 298 K. (d) Changes of the proton signal intensities assigned to the water cluster and dissolved water with time at 283 K. The residual proton signals of benzene in (a–c) are from residual benzene in the benzene-d6 solvent.
