WebJul 13, 2009 · It should be noted that while photolysis formally refers to the cleavage of a chemical bond, the term “flash photolysis” is used in conjunction with the use of the time-resolved approach described above to follow the kinetics of a chemical reaction. Thus, the term “flash photolysis” should not be considered to imply bond breaking. Figure 2. WebOct 23, 2024 · Photolysis: The light reaction initiates when the chlorophyll absorbs light. It causes one of its electrons to move to a higher energy state. The excited electron is transferred to an acceptor molecule and is replaced by an electron from water (H 2 O). john robinson mayflower https://tfcconstruction.net
