Both excimers and exciplexes have attracted the attention of molecular physicists and photochemists over the last decade. Owing to the use of laser photolysis, measurements of short-lived photocurrents, and pulse spectrofluorimetry, it became possible to satisfactorily explain photophysical processes occurring in molecular systems [1]. Excimers and exciplexes provide important steps of many pho...

[1] The tropical oceans are a source of reactive bromine to the atmosphere in the form of short-lived brominated methanes as bromoform (CHBr3) and dibromomethane (CH2Br2). Elevated atmospheric concentrations above the tropical oceans are related to oceanic supersaturations of the compounds and especially to upwelling regimes. Although the sources of these brominated gases in the open ocean are ...

Quasielastic electron scattering from gaseous species at high momentum transfer was recently reported for the first time [Cooper et al., J. Electron Spectrosc. Relat. Phenom. 155, 28 (2007)]. The first results for CH(4) and CD(4) were well explained by a classical electron Compton scattering picture in which the electron scatters independently from each atom rather than the molecule as a whole....

L-Nτ-methylhistidine methyl ester, MeHisOMe, has been employed as a potential ligand to mimic the histidine brace-type coordination of copper ions in enzymes such particulate methane monoxygenase or lytic polysaccharide monooxygenases. MeHisOMe was prepared by double-methylation ester. Subsequently, its complexation diphosphine copper(I) precursors [Cu(P^P)(MeCN)2]BF4 tested, which led complexe...
