| Outline of Final Research Achievements |
We have investigated the hydrogen bonding states of nano-confined water by using Soft X-ray emission spectroscopy. It is known that XES spectrum of water shows a split of the lone-pair (1b1) peak which has been interpreted as arising from structures with distorted hydrogen bonds (1b1'') and from tetrahedrally hydrogen-bonded structures (1b1'). We found the relative population of 1b1’ peak decreased along with a decrease of the micelle size, that is, the hydrogen bonding of water molecules confined in the reverse micelle becomes weaker than that of bulk water when a diameter of the reverse micelle is around 2 nm.
