    "abstract": "Single-shot ultrafast spectroscopy based on the frequency encoding of\ntransient absorbance kinetics (FDSS) is demonstrated. These kinetics are\nsampled spectrally using linearly chirped pulses derived from a Ti:sapphire\nlaser. A variable length grating pair compressor is used to provide group\nvelocity dispersion out to -1.6 ps^2 and achieve the sampling of 512 channels\nper a 2-to-160 ps window with sensitivity \u003e 5e-4. The possibilities of FDSS are\nillustrated with studies of three photon ionization of liquid water and\none-photon excitation of a thin-film",
