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 …

Ground and excited state processes induced by hydrogen bond formation are discussed for
a family of heterocyclic compounds which possess both a proton donor (pyrrole NH group) …

Proton or hydrogen transfers, basic chemical reactions, proceed either by thermally
activated barrier crossing or via tunneling. Studies of molecules undergoing single or double …

We study the mechanism of proton transfer (PT) in the aqueous acid− base reaction
between the photoacid 8-hydroxy-1, 3, 6-pyrenetrisulfonic acid (HPTS) and acetate by …

Contemporary progress regarding guest/host types of excited‐state double proton transfer
has been reviewed, among which are the biprotonic transfer within doubly H‐bonded …

The excited-state double proton transfer (ESDPT) process of dipyrido [2, 3-a: 3′, 2′-i]
carbazole (DPC) in ethanol (EtOH) solvent is investigated using density functional theory …

Proton transfer reaction is studied for 1 H-pyrrolo [3, 2-h] quinoline− water complexes
(PQ−(H2O) n, n= 0− 2) in the ground and the lowest excited singlet states at the density …

Photophysical studies of a series of over 20 compounds based on pyrrole, indole, and
carbazole chromophores were carried out in protic, nonpolar, and polar solvents. Absorption …

Ground-and excited-state long-range prototropic tautomerization were studied for a series of
7-hydroxyquinoline-8-carbaldehydes (7-HQCs) by 1H and 13C NMR spectroscopy …

Studies of excited state multiple proton transfer (ESMPT) are paramount importance for both
