Plants contain chlorophyll-type molecules, which play a vital role in photosynthesis for several reasons. Photosynthesis, a well-known process, involves two distinct photosystems: Photosystem I (PSI) and Photosystem II (PSII). PSI acts as the catalyst in this reaction, utilizing light to transfer electrons from plastocyanin to ferredoxin. PSII serves as a catalyst and initiates the photosynthetic process. The negative charge is localized on a single chlorophyll molecule instead of two, as observed in the PSI dimer. To investigate electron transfer in PSII, it is imperative to understand the behavior of the chlorophyll a itself in gas phase.
