Subwavelength Patterning Microscopists have recently achieved fluorescence imaging at subwavelength resolution by focusing one beam of light in a halo around another beam, thereby quenching the glow of fluorescent dyes in all but the very center of t

Vibrational sum-frequency spectroscopy (VSFS) has become a widely used tool for studying molecules at interfaces. While VSFS data are often interpreted in terms of static structure, Wei and Shen demonstrated that orientational dynamics that occur on

Pure ν1 vibrational dephasing of triiodide is recorded in ethanol and methyl-tetrahydrofurane solutions from 300 to 100 K, for the vibrational fundamental and its first overtone. Using impulsive Raman spectroscopy, dephasing is demonstrated to be ho

Coherent control of I3- ground state dynamics in ethanol and acetonitrile solutions is demonstrated. The method is based on impulsive excitation creating a dynamic hole employing sub 30 fsec tunable UV laser pulses. The target of control was to incre

The vibrational dephasing of triiodide ions is studied in ethanol solutions, at temperatures ranging from room temperature to 80K. The dynamics of dephasing is demonstrated to be homogeneous throughout that range, and not to be dominated by populatio

Geminate recombination following impulsive ultraviolet photolysis of cryogenically cooled triiodide in ethanol is followed with 100 fs time resolution. Caged fragments either recombine directly and vibrationally relax within picoseconds or produce a

We demonstrate the use of extreme ultraviolet (EUV) light for time-resolved measurements of the photothermal and photoacoustic response of materials. By using wavelengths that are 20× shorter than visible light, we demonstrate the potential for dram
