title: Pre-resonance-stimulated Raman scattering for water bilayer structure on laser-induced plasma bubble surface.
abstract: Pre-resonance-stimulated Raman scattering (PSRS) from water molecules in the air/water interfacial regions was studied when the laser-induced plasma bubble was generated at the interfaces. A characteristically lower Raman shift of OH-stretching vibrational modes of water molecules at around 3000  cm(-1) (370 meV) was observed, in which the mechanisms were possibly attributed to the strong hydrogen bond in a well-ordered water bilayer structure that was formed on a laser-induced plasma bubble surface. Simultaneously, the PSRS of ice Ih at about 3100  cm(-1) was obtained, which also belonged to the strong hydrogen bond effect in ice Ih structure.
