In molecules, two types of excited states can exist;
a) The singlet state is relatively short‐lived and contains electrons with opposite (antiparallel) spins.
b) The more long‐lived triplet state has electron spins that are aligned (parallel).

Triplet states generally have much longer lives (take longer to de‐excite) than singlet states and are at a lower energy level.

Absorption of blue or red light causes the chlorophyll molecule to convert into an excited state, with blue light absorption resulting in a higher excited state because of the greater energy of blue light relative to red light.
