Using muon spin rotation spectroscopy, researchers from Japan and Canada have successfully captured the rapid conversion of ...

Single crystals of 5,5′-diethylbarbituric acid (barbital) were irradiated with 4.0-MeV electrons and studied by ESR in the temperature range 77 to 300 K. Altogether, five radicals have been identified ...

Haze is formed when a cocktail of various gaseous pollutants is oxidized and forms particulate matter diffusing sunlight. This process is mainly mediated by hydroxyl radicals (OH), and researchers ...

Photochemical reactions begin by absorption of energy in the form of light, and involve formation of free radicals and transient excited states whose physical and chemical properties are very ...
