| Research Abstract |
We developed a new low frequency Raman spectroscopy for elucidating melting processes of ionic liquids. It enables fast and simultaneous monitoring of various aspects of melting : increase of temperatures, loss of lattice vibrations, and intramolecular structure change. Several new phenomena are found,(1) a transient crystalline state existing at temperatures higher than the melting point,(2) delay of intramolecular conformational changes during the melting, and(3) thermal non-equilibration of anions and cations in an ionic liquid. The third result will lead to a new concept,"molecular temperature", which is useful for discussing thermal inhomogeneity of general liquids as well as ionic liquids.
