Flash photolysis. Researcher loading samples that will undergo flash photolysis, a method of investigating fast photochemical reactions. Exposure to very brief, intense flashes of light allows the resulting products to be identified from their absorption spectra, the unique pattern of light wavelengths they absorb. Photographed at Durham University, UK.
Model release available. Property release not required.
