<P> In 2012, Renger expressed the idea of internal changes of water molecules into typical oxides in different S - states during water splitting . In 2017, Dolai showed almost complete concept of water splitting by the way of structural analysis of S - states and developed oxides from the water molecules . </P> <P> Dolai's Diagram of S - states: Dolai's diagrams are perfect pictures of different S - states in water - splitting during photosynthesis . These diagrams can express complete figures of intermediate S - states as well as the development of typical oxides (monoxide (2H2O), hydroxide (OH. H2O), peroxide (H2O2), super oxide (HO2) and di - oxygen (O2)); which are formed due to interchange of water molecules in S - states . The arrangement of hydrogen bonding is main criteria of the diagrams . The effect of photon (hv), emission of electron (e) and production of hydrogen ion (H+) from water molecules can be shown by the diagrams in a more specific way of experimental detection . The diagrams almost completely analyze the pathway of water - splitting in photosynthesis . </P>

When does the splitting of water occur in photosynthesis
