The origin of ions in matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry
is currently a matter of active research. A number of chemical and physical pathways have …

In nano-ESI MS, the qualitative and quantitative characteristics of mass spectra vary
considerably upon the use of different spraying conditions, ie, aperture of the spraying …

We developed a multiresidue method for the target and suspect screening of more than 180
pharmaceuticals, personal care products, pesticides, biocides, additives, corrosion …

The real‐time dynamics of hydrogen‐atom‐transfer processes under collisionless conditions
are studied using femtosecond depletion techniques. The experiments focus on the methyl …

Photoacids undergo an increase in acidity upon electronic excitation, enabling excited-state
proton transfer (ESPT) reactions. A multitude of compounds that allow ESPT has been …

“Spectral and acidity data are for 1 X 4 M aqueous solutions. Lifetime data are in
Me2SO.'From absorption titration.“Calculated from emission maxima using the Forster cycle …

This article demonstrates experimental proof of excited state 'solvent-to-chromophore'proton
transfer (ESPT) in the isolated gas phase PBI (2, 2′-pyridylbenzimidazole)–CH3OH …

The interaction of polycyclic aromatic hydrocarbon molecules with water (H2O= W) is of
fundamental importance in chemistry and biology. Herein, size-selected microhydrated …

Intermolecular charge-and proton-transfer processes, ie, the motion of proton associated
with the change of the electronic structure in hydrogen-bonded complexes, are of great …

We have experimentally demonstrated conclusive evidence of solvent-to-chromophore
excited-state proton transfer (ESPT) as a deactivation mechanism in a binary complex …
