    "abstract": "\"Single-shot\" ultrafast spectroscopy based on the frequency encoding of\ntransient absorbance kinetics using chirped probe pulses is analyzed\ntheoretically. FDSS has an advantage over pump-probe spectroscopy in a\nsituation where the \"noise\" is dominated by amplitude variations of the signal.\nUnlike \"single-shot\" techniques based on spatial encoding of the kinetics, no a\npriori knowledge of the excitation profile of the pump is needed. FDSS\nspectroscopy can be used for many types of samples, liquid or solid, including\nthose comparable in thickness to the wavelength of the probe light. Another\nadvantage is that due to the interference of quasimonochromatic components of\nthe chirped probe pulse, an oscillation pattern near the origin of the FDSS\nkinetics emerges. This interference pattern is unique and can be used to\ndetermine the complex dielectric function of the photogenerated species.",
