“…50 The frequency dependent response of pure water is obtained from experimental IR data. 11,12,14,51 These ingredients were used to calculate the total solvation energy, E(), 19,52 of eosin in water. A relationship between the solvation energy and the solvation correlation function, S(t) 53 can be derived 54 and expressed by…”

“…[16][17][18][19][20] Experimentally, time-domain techniques such as fluorescence up-conversion, 2 optical Kerr effect ͑OKE͒ [3][4][5] and THz spectroscopy, 6,7 in addition to frequency-domain spectroscopies such as Raman [8][9][10] and infrared ͑IR͒ [11][12][13][14][15] have been employed to gain a detailed understanding of the intermolecular and intramolecular motions and dynamics of liquid water. Theoretical studies of aqueous solvation 16 have included simulations ranging from predictions of the IR and Raman spectra, [20][21][22][23] to calculations of the solvation relaxation function S(t), 17,19,23,24 and the third order response.…”

Three-pulse photon echo peak shift measurements were employed to study aqueous solvation dynamics. A new perspective of dielectric continuum theory [X. Song and D. Chandler, J. Chem. Phys. 108, 2594 (1998)] aided in characterizing the system-bath interactions of eosin in water. Application of this theory provides solvation energies, which were used within the spectral density representation ρ(ω), to calculate the experimental peak shift. Simulations with only solvation contributions to ρ(ω), where a substantial amplitude of the solvation occurs within ∼30 fs, are remarkably consistent with our data. Furthermore, simulations using this theoretical solvation spectral density and an experimentally determined intramolecular spectral density yield an excellent total simulation of the peak shift data over the entire dynamic range. Our experimental results substantiate predictions that interaction-induced polarizability effects, contributing via a ∼180 cm−1 band in the spectral density, influence the initial dynamics.

A practical version of a homodyne method for measuring the complex permittivity of high loss liquids at 3 and 9 GHz is described. The systematic errors are discussed in detail, because the homodyne method seems to be suitable as a simple standard method for precise measurements. The results of measurements on water in the temperature range 6 °C-45 °C are presented. The determination of all five parameters of the Debye function is possible. Finally, accuracy limiting factors for the determination of the relaxation parameters are discussed in detail.

“…Water has been used in DSS measurements 2,42 and its dielectric response function is available at a high level of accuracy over a wide range of frequencies. [83][84][85][86] Equation ͑55͒ shows that the effect of the finite pump pulse duration on the DSS depends on the difference between ⌬(t) and ⌬ 1 (t), Eqs. ͑37͒ and ͑52͒.…”

The time-evolution of the fluorescence spectrum of a dissolved chromophore excited by an ultrafast pump pulse is considered. The average value of the energy difference of the solute in its excited and ground states is used to describe the relaxation of the maximum of the transient fluorescence spectrum to its equilibrium value ͑dynamic Stokes shift, DSS͒. A simple formula for the normalized DSS is obtained which generalizes an earlier standard classical expression and includes the effect of a pump pulse of finite duration. As an example, dielectric dispersion data are used for a dipolar solute in water to estimate the quantum correction to the standard DSS expression. The correction is negligible when the frequency of the pump pulse is close to the maximum in the absorption spectrum, but a deviation from the standard formula can be expected for the pump pulse tuned to a far wing of the absorption band of the chromophore. An expression is given for this deviation.
