In this short review, we attempt to unfold various aspects of excited-state intramolecular
proton transfer (ESIPT) from the studies that are available up to date. Since Weller's …

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 …

Over many millennia, humankind has thought to explore phenomena on an ever shorter time
scale. In this race against time, femtosecond resolution (1 fs= 10− 15 s) is the ultimate …

This tutorial review describes in a brief historical perspective the most important organic
compounds that exhibit photochromism in the crystalline state since its discovery in 1867 up …

In this article we discuss the progress made in understanding intermolecular and
intermolecular reactions of proton (or hydrogen-atom) transfer. Femtosecond real-time …

Dyes undergoing excited-state intramolecular proton transfer (ESIPT) are known to present
large Stokes shifts as a result of the important geometrical reorganisation following photon …

HYDROGEN bonds commonly lend robustness and directionality to molecular recognition
processes and supramolecular structures1, 2. In particular, the two or three hydrogen bonds …

We present a review of wave-packet dynamics, with a focus on'femto-chemistry'. We review
basic theory and simple properties of wave-packets, the application of two-state models to …

A detailed analysis of the excited-state intramolecular proton transfer (ESIPT) of 2-(2 '-
hydroxyphenyl) benzothiazole and the associated wave packet motion is presented. It is …

Silica-based materials (SBMs) are widely used in catalysis, photonics, and drug delivery.
Their pores and cavities act as hosts of diverse guests ranging from classical dyes to drugs …
