Abstract

Resorcinol molecules and those solvated with solvent water molecules were isolated in the gas phase from a liquid beam of an aqueous solution of resorcinol by resonant vibrational excitation of solvent water molecules under IR-laser irradiation. The spatial distribution of the ejected species at various delay times from the IR-laser irradiation indicates that two different isolation mechanisms operate: One dominates in a time range shorter than ~1 μs (early-time domain), and the other in a time range longer than ~1 μs (late-time domain). A time-dependent measurement of the liquid-beam profile by optical diffraction shows that the beam has a smooth surface in the early-time domain, whereas in the late-time domain the surface roughness overweighs the wavelength of the illumination laser.
