Two-color Transient Grating Spectroscopy of a Two-level System

“…The laser pulses have a duration of 45 fs for all the experiments described. A more detailed description of the pulse generation and experimental set up can be found in reference 16. ) is sufficient to place the window near the bottom of the excited state surface, since no pronounced maximum in the signal is observed.…”

Spectrally resolved femtosecond nonlinear spectroscopy of vibrational coherence relaxation in molecules

“…Both of these investigations [11,13] have been onecolour PE experiments, which can be modelled in terms of two-level systems and thus the PE spectra are not expected to exhibit structure. Agarwal et al [14] have recently reported two-colour three pulse echo peak shift measurements and have shown that this technique can be useful for studying correlations between reactant and product states because the technique can probe different parts of the potential surface. The time evolution of the peak shift is dependent on the combination of the pulses wavelengths.…”

Ultraviolet transient absorption, transient grating and photon echo studies of aqueous tryptophan

“…These techniques are also sensitive to both the ground and the excited state dynamics. While being widely used in the visible and IR spectral regions [31][32][33][34][35][37][38][39][40][41][42], PE and TG techniques have rarely been attempted in the UV due to, in particular, the significant non-resonant contributions from the solvent. Following the two-pulse PE experiments by Zimdars et al [43], we implemented the three-pulse UV PE [44][45][46].…”
