singlet state


Also found in: Dictionary, Thesaurus, Encyclopedia.

sin·glet state

a transient, excited state of a molecule (for example, of chlorophyll, on absorbing light) in which a molecule can release energy as heat or light (fluorescence) and thus return to its initial (ground) state; it may alternatively assume a slightly more stable but still excited state (triplet state), with an electron still dislocated as before but with reversed spin.

singlet state

[sing′glit]
a state of an atom or molecule in which all electrons have paired spins.

Triplet oxygen is a good energy acceptor and it can be excited to its singlet state by energy transfer from a photosensitizer.
The process is related to excitation of benzophenone (BP) by far UV radiation (250 nm) to a singlet state [S.
