Water in the gas phase.
Switch on the weather forecast any evening and one is left in no doubt as to the importance of water in the Earth’s atmosphere: will the water be gaseous (humidity), liquid (clouds, rain), solid (snow, ice or hail) or taken up by aerosol (haze) particles? The long-term role of water in our climate, and of course any change in our climate, is no less profound. The water vapour is both the domina...
متن کاملProteins, lipids, and water in the gas phase.
Evidence from mass-spectrometry experiments and molecular dynamics simulations suggests that it is possible to transfer proteins, or in general biomolecular aggregates, from solution to the gas-phase without grave impact on the structure. If correct, this allows interpretation of such experiments as a probe of physiological behavior. Here, we survey recent experimental results from mass spectro...
متن کاملGas-phase infrared spectrum of the protonated water dimer.
The protonated water dimer is a prototypical system for the study of proton transfer in aqueous solution. We report infrared photodissociation spectra of cooled H+(H2O)2 [and D+(D2O2] ions, measured between 620 and 1900 wave numbers (cm-1). The experiment directly probes the shared proton region of the potential energy surface and reveals three strong bands below 1600 cm-1 and one at 1740 cm-1 ...
متن کاملRevealing charge-transfer effects in gas-phase water chemistry.
An understanding of the interactions involving water and other small hydrogenated molecules such as H(2)S and NH(3) at the molecular level is an important and elusive scientific goal with potential implications for fields ranging from biochemistry to astrochemistry. One longstanding question about water's intermolecular interactions, and notably hydrogen bonding, is the extent and importance of...
متن کاملThe gas phase reaction of singlet dioxygen with water: a water-catalyzed mechanism.
Stimulated by the recent surprising results from Wentworth et al. [Wentworth, A. D., Jones, L. H., Wentworth, P., Janda, K. D. & Lerner, R. A. (2000) Proc. Natl. Acad. Sci. USA 97, 10930-10935] that Abs efficiently catalyze the conversion of molecular singlet oxygen ((1)O(2)) plus water to hydrogen peroxide (HOOH), we used quantum chemical methods (B3LYP density functional theory) to delineate ...
