▪ Abstract Chemical reaction and optical dynamics in the liquid phase are strongly affected
by specific solute-solvent interactions. The dynamical part of this coupling leads to energy …

Several closely related third‐order nonlinear time‐resolved spectroscopic techniques,
pump/probe transient absorption, transient grating, and three pulse stimulated photon echo …

We show how in the framework of the multimode Brownian oscillator model the system−
bath correlation function can be derived from conventional and time-gated stimulated photon …

The underlying dynamics of the B800 absorption band in isolated LH2 of Rb. sphaeroides at
room temperature is studied by transient absorption, transient grating, and photon echoes …

In view of the rapid growth in both experimental and theoretical studies of multiphoton
processes and multiphoton spectroscopy of atoms, ions and molecules in chemistry …

In this work, we demonstrate the use of broad-band pump–probe spectroscopy to measure
femtosecond solvation dynamics. We report studies of a rhodamine dye in methanol and …

The microscopic details of how a solution responds to changes in a solute are now
becoming experimentally accessible at the kinds of times that should allow us to follow even …

The excited-state dynamics of the radical cations of perylene (PE•+), tetracene (TE•+), and
thianthrene (TH•+), as well as the radical anions of anthraquinone (AQ•-) and …

For both two-and three-level systems, theoretical descriptions of two-color transient grating,
transient dichroism, and transient birefringence spectroscopies were presented. The two …

The solvation dynamics of an organic dye, IR140, in methanol, ethanol, and in a series of six
alkanenitriles has been investigated using the transient grating technique. In all solvents, the …
