| Research Abstract |
Electronic structure of low temperature liquid water was measured by soft X-ray emission spectroscopy. A shoulder peak that corresponds to breaking of hydrogen bond appeared even in the ice phase, which is probably originated from core-induced dynamics. Electronic structure of low temperature acetonitrile-water mixture exhibited little change with increase of microheterogeneity at low temperature, which implies difference in the size of density fluctuation and measurement region of soft X-ray emission.
