Frequency-domain "single-shot" (FDSS) transient absorption spectroscopy using a variable-length grating pair compressor
Ilya A. Shkrob, Dmitri A. Oulianov, Robert A. Crowell
Single-shot ultrafast spectroscopy based on the frequency encoding of transient absorbance kinetics (FDSS) is demonstrated. These kinetics are sampled spectrally using linearly chi…
Solvation, relaxation, and geminate recombination of electrons generated by two 200 nm photon ionization of liquid H2O and D2O
Rui Lian, Robert A. Crowell, Ilya A. Shkrob
Temporal evolution of transient absorption spectra for pre-solvated electron (e-) generated by biphotonic (200 nm) ionization of liquid H2O and D2O has been studied on femto- and p…
Ultrafast studies on the photophysics of matrix-isolated radical cations of polycyclic aromatic hydrocarbons: implications for the Diffuse Interstellar Bands (DIB) problem
Liang Zhao, Rui Lian, Ilya A. Shkrob +5
Rapid, efficient deactivation of the photoexcited PAH cations accounts for their remarkable photostability and have important implications for astrochemistry, as these cations are…
Frequency-domain "single-shot" (FDSS) ultrafast transient absorption spectroscopy using compressed laser pulses. Part II. Supplemetary Material
Ilya A. Shkrob, Dmitri A. Oulianov, Robert A. Crowell +1
Single-shot ultrafast absorbance spectroscopy based on the frequency encoding of the kinetics is analyzed theoretically and implemented experimentally. In Part II of the series, ar…
