Re: Resonance transfer

Once case of resonance transfer is when an electron in an excited state drops to a more stable state and passes the energy to another electron, exciting that electron ...

Re: What are delocalized electrons?

... bonds", that's a mistake. The point is the hybridization state of the carbons, i.e. sp2 hybridization (see wiki ), which leaves one ... normal p-orbitals and thus these electron need smaller energy to be excited (look for molecular orbitals ). They are anchored in the chloroplasts! ...

Re: Why do intact chloroplasts fluoresce?

... thought that the reason why chlorophyll fluoresces is because the photoexcited electrons spontaneously drop back down to the ground state. This drop doesn't happen in an intact chloroplast, because the excited electron is captured ...
