| Research Abstract |
We showed that a transient crystalline structure of anthracene exists in its melting. Lattice vibrations of the'' super-heated'' crystal, which is only seen during the melting, are different to those of the stationary state. We improved the fast low frequency Raman spectroscopy for simultaneous monitoring the optical image of the sample under microscope. It enables sub-second time-resolved and micrometer space-resolved tracing of the appearance(or disappearance) of lattice vibrations with simultaneous monitoring the morphology changes. It will be a new method for molecular-level and real-time tracing structural change of a small crystal during its phase transitions.
