“…However, the rapid destructive interference between different frequencies makes it unlikely that 3PEPS or TG will be especially incisive techniques for the study of such processes. It is possible that the mode suppression techniques introduced by Shank et al 31,78,79 and Wiersma et al 80 may be of value in reducing this interference, but with many mode systems very complex fields would be necessary and the technique does not seem viable at present.…”

We present numerical simulations of WD-3PEPS and WD-TG signals of two probe molecules: Nile Blue and N,N-bisdimethylphenyl-2,4,6,8-perylenetetracarbonyl diamide to investigate the influence of intramolecular vibrations in the signals. By varying the excitation wavelength, we show that the different initial conditions for the vibrational wave packets significantly affect the signals, especially through the contributions associated with high frequency modes, often neglected in experimental analyses. We show that the temporal properties of both WD-TG and WD-3PEPS signals display sensitivities to both the excitation wavelength and the vibronic structure of the specific probe molecule used. Several mechanisms for generating vibronic modulations in the signals are discussed and their effects on the signals are described. Quantitative agreement between experiment and simulated signals requires accurate characterization of the laser pulses, specifically the magnitude and sign of chirp has a significant effect on the initial temporal properties of the signals. We provide a description of the experimental considerations required for accurate determination of molecular dynamics from 3PEPS and TG experiments and conclude with a brief discussion of the implications of our results for previous analyses of such experiments.

“…Whereas previous studies have considered non-Markovian effects in dephasing dynamics within the framework of phenomenological stochastic models, [15][16][17][18][19] the scheme proposed here is more general and based on describing the dephasing process in terms of a nonMarkovian generalized quantum master equation. A central role within this formulation is played by the memory kernel, which is explicitly dependent on the initial solvent configuration.…”

The electronic dephasing dynamics of a solvated chromophore is formulated in terms of a non-Markovian master equation. Within this formulation, one describes the effect of the nuclear degrees of freedom on the electronic degrees of freedom in terms of a memory kernel function, which is explicitly dependent on the initial solvent configuration. In the case of homogeneous dynamics, this memory kernel becomes independent of the initial configuration. The Markovity of the dephasing process is also the most conveniently explored by comparing the results obtained via the non-Markovian master equation to these obtained via its Markovian counterpart. The homogeneous memory kernel is calculated for a two-state chromophore in liquid solution, and used to explore the sensitivity of photon echo signals to the heterogeneity and non-Markovity of the underlying solvation dynamics.

“…Background-free three-pulse DFWM can also coherently control wavepacket motions [28,29] and, it is reported that coherent vibrations can be selectively switched from that in the ground state to that in the excited state in the case of neat iodine vapor [30,31]. Tuning the pump and probe wavelengths will also enable access to the 6 details of the wavepacket dynamics.…”

Coherent nuclear wavepacket motions were monitored by three types of femtosecond time-resolved spectroscopy, namely, transient absorption measurement utilizing white-light supercontinuum (WC-TA), degenerate four-wave-mixing (DFWM), and pump-probe (PP) measurements, for an ultrafast intermolecular electron transfer (ET) system with a dye molecule, oxazine 1 (Ox1), dissolved in an electron donating solvent, N,N-dimethylaniline (DMA). Vibrational frequencies of the wavepacket motion in the excited and in the ground states were 560-562 and 567-569 cm-1 , respectively, with only a few frequency difference of 5-9 cm-1 , which were clearly distinguishable by the highly accurate measurements. In DMA, the excited state wavepacket motion declined with time constant of 160-240 fs which is somewhat longer than that of the ultrafast ET; 60-80 fs.
