Current computer models may underestimate levels of ground-level ozone A team of scientists has, for the first time, completely characterized an important chemical reaction that is critical to the formation of ground-level ozone in urban areas. The team's results indicate that computer models may be underestimating ozone levels in urban areas during episodes of poor air quality (smoggy days) by as much as five to 10 percent. Ground level ozone poses significant health hazards to people,...

Mapping the structure of protonated water clusters Water molecules are continuously forming short-lived networks called clusters. These can in turn bind positively charged protons, and such clusters can provide active functional groups in proteins. Using infrared spectroscopy, it is possible to determine the bond strengths, geometrical structures and chemical properties of protonated water clusters. In order to measure the spectrum of molecular vibrations in clusters it is, however, necessary...
