The dynamics of the excited-state intramolecular proton transfer of 10-hydroxybenzo[h]quinoline (10-HBQ) and the associated coherent nuclear motion were investigated in solution by femtosecond absorption spectroscopy. Sub-picosecond transient absorption measurements revealed spectral features of the stimulated emission and absorption of the keto excited state (the product of the reaction). The stimulated emission band appeared in the 600-800-nm region, corresponding to the wavelength region of… Expand

Non-Condon Effect on Ultrafast Excited State Intramolecular Proton Transfer.
TLDR
The reaction dynamics of excited state intramolecular proton transfer of 2,2'-dihydroxy-azobenzene was investigated by means of white-light supercontinuum femtosecond transient absorption spectroscopy, indicating that the transition strength of the product state is dynamically modulated by a nuclear wavepacket motion (non-Condon effect).

TLDR
Theoretical calculations of the vibrational reorganization energies reproduce the experimental spectrum of the nuclear wave packets and corroborate the conclusions about the dynamics of intramolecular charge transfer of 8-aminopyrene-1,3,6-trisulfonic acid occurring in the excited state by time-resolved fluorescence (TF) and TF spectra.

Tracking of the nuclear wavepacket motion in cyanine photoisomerization by ultrafast pump-dump-probe spectroscopy.
TLDR
A nuclear wavepacket motion in photoisomerization of a prototype cyanine dye is studied by ultrafast pump-dump-probe measurements in solution and a rapid migration as well as broadening of the wavepackets manifests a continuous nature of the structural dynamics and provides an intuitive visualization of this ultrafast reaction.

Vibrational coherence transfer in the ultrafast intersystem crossing of a diplatinum complex in solution
TLDR
A significant shortening of the intersystem crossing (ISC) time from the lowest singlet to the lowest triplet state is found, allowing for a transfer of vibrational coherence, observed in the course of an ISC in a polyatomic molecule in solution. Expand
