Dear FRIEND HERE THE ANSWER :
Triplet excited state is the state attained after the electron gets excited from singlet ground state to singlet excited state and then it looses a part of energy to reach the triplet state. In triplet state excited electrons are in parallel spin i.e excited electrons are not paired with the ground state but in singlet state excited electrons are in opposite spin i.e. excited electrons are paired with the ground state.
After excitation to first singlet state some of the electrons reaches another higher energy state called second singlet state which is more unstable than singlet state. Therefore second singlet state looses its energy quickly than the singlet state to reach ground state. Chlorophyll molecule of reaction centre absorbs light and follow these transition states to deliver excited electrons to the phaeophytin by PSII molecule and to ferrodoxin by PSI.
These states are the transition states which are present in the atom of chlorophyll molecule.

hey ❕ here's your answer
A pair of electrons in the same energy state say ground state can stay in opposite spin states say :up and down with spin states characterised by +1/2 and -1/2 in units of h_bar. So the total spin S= 0 ; thereby the multiplicity 2S+1 =1 and this is called singlet state.
