Much of chemistry is concerned with the study of reactions and processes in solution, that is,
where liquids are used as solvents. 2, 3 The solvent is the (excess) liquid phase in which …

Ultrafast photochemical reactions in liquids occur on similar or shorter time scales compared
to the equilibration of the optically populated excited state. This equilibration involves the …

We review recent advances in experimental methods for high spatial-resolution and high
time-resolution thermometry, and the application of these and related methods for …

▪ Abstract Time-resolved infrared (IR) and Raman spectroscopy elucidates molecular
structure evolution during ultrafast chemical reactions. Following vibrational marker modes …

Understanding a chemical reaction ultimately requires the knowledge of how each atom in
the reactants moves during product formation. Such knowledge is seldom complete and is …

We show several pieces of Raman spectroscopic evidence that are indicative of local
structure formation in imidazolium-based ionic liquids. Low-frequency Raman spectra of C n …

Ultrafast excited-state structural dynamics of [CuI (dmp) 2]+(dmp= 2, 9-dimethyl-1, 10-
phenanthroline) have been studied to identify structural origins of transient spectroscopic …

The electronic and vibrational relaxation of photoexcited trans-azobenzene was investigated
in solution by picosecond time-resolved Raman spectroscopy. Picosecond time-resolved …

We propose a novel method to characterize hydration states from dielectric responses of
solutions in terahertz (THz) frequency region. Hydration states can be evaluated …

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 …
