Photolysis reaction
WebThese photolysis products can be detected at low concentrations directly or after conversion to suitable derivatives by UV–Visible, fluorescence, or electrochemical detection. The primary reagent for photolysis reactions are photons, and their reactivity can be controlled to some extent by varying the excitation wavelength and intensity. WebThe photolysis of water is an important part of the process of photosynthesis. Describe what happens in the photolysis of water (2 marks) Water breaks down to form H+, oxygen and electrons. Light excites the electrons to photosystems ATP and reduced NADP are two products of the light-dependent reactions.
