    Notes: Abstract The theory of Interferometric Coherent Raman Scattering (ICRS) using “twin” broadband fields has recently been extended to include both resonant and nonresonant contributions to the signal. It is reviewed here. Valid for both ICARS and ICSRS, it is applied to new ICARS experiments on neat toluene and on alcoholic solutions of a methine dye. In each case the damped Rabi Detuning Oscillations (RDO), that are characteristic of ICRS, lead directly to vibrational frequencies and their dephasing times. The theory is also applied as a new way to determine the ratio of the nonresonant to resonant hyperpolarizabilities, accurately for toluene, and approximately for the methine dye solution whose (vibrationally) “nonresonant” contribution is negative.

    Structural changes in excited states and photoisomers determined by time-resolved Raman scattering (1994)
    Springer
    Applied physics 59 (1994), S. 403-414 
    Details
    ISSN: 1432-0649
    Keywords: 33.20.Fb ; 42.65.Dr
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Molecules in the excited singlet and triplet state and photoproducts occuring after photoisomerization or proton transfer are investigated by time-resolved resonance Raman and resonance CARS spectroscopy with nanosecond time resolution. From the time-resolved spectra information on structures and bond strengths of these short-lived species and on their kinetics are obtained.

    Thermal Raman shift of the C60 tangentialA g mode (1995)
    Springer
    Applied physics 61 (1995), S. 171-175

    Notes: Abstract Fullerence C60 exhibits a continuous and reversibleA g (2) mode softening from 1469 to 1459 cm−1, which is linear with laser power up to 21.9 kW/cm2 for C60 crystals under vacuum. Model calculations taking into account the temperature distribution that is induced by the Gaussian intensity profile of the laser beam reproduce the measured frequency shifts. A thermal conductivity of microcrystalline fullerene of 0.27(±0.03) W/mK is derived from this numerical analysis.
