flash photolysis
flash photolysisn. A method of investigating fast photochemical reactions by exposure to very brief, intense flashes of light and spectroscopically analyzing the resulting products.flash photolysis n (Chemistry) physics a technique for producing and investigating free radicals. A low-pressure gas is subjected to a flash of radiation to produce the radicals, subsequent flashes being used to identify them and assess their lifetimes by absorption spectroscopy Translationsflash photolysis
flash photolysis[′flash fə‚täl·ə·səs] (physical chemistry) A method of studying fast photochemical reactions in gas molecules; a powerful lamp is discharged in microsecond flashes near a reaction vessel holding the gas, and the products formed by the flash are observed spectroscopically. |
