Web- In this video we will be talking about a new type of reaction called "Redox Reaction". And these are very commonly found. Photosynthesis is an example of redox reaction. The chemical reaction that happens within a battery which powers your phone or laptop devices, this is also an example of redox reaction. WebPhotoinduced electron transfer. Photoinduced electron transfer ( PET) is an excited state electron transfer process by which an excited electron is transferred from donor to acceptor. [1] [2] Due to PET a charge separation is generated, i.e., redox reaction takes place in excited state (this phenomenon is not observed in Dexter electron transfer ).
