As a result, there is only one spectral line of a singlet state. In contrast, a doublet state contains one unpaired electron and shows splitting of spectral lines into a doublet; and a triplet state hastwo unpa
What is singlet oxygen and can I measure it using photoluminescence? Singlet oxygen is produced from a photosensitizer molecule reacting with ground state oxygen.
Triplet-triplet annihilation (TTA) is the energy transfer process where two molecules in their triplet excited state interact to produce two singlet states.
These mechanisms rely on the excitation of the sensitizer from its electronic ground state to the fluorescent singlet state, which is in turn transformed into the longer-lived triplet state. Efficient of this metastable state is required because it is the interaction of the triplet state with ...
The only thing I can clearly guess is that you discuss two spins in the singlet state, Angular-momentum conservation can now be discussed for the usual example of Bohm's version of EPR: The spin-singlet state is prepared by the decay of a spin-0-particle in its rest frame (and there'...

A fluorescence event consists of an electron emitting light when it returns from singlet excited state to singlet ground state. The lowest excited triplet state is energetically very close to the singlet ground state, and statistically triplet states outnumber singlet states by a ratio of 3:1. ...
PDT involves topical or systemic administration of a photosensitizer, followed by illumination with light of a suitable wavelength to excite it to its singlet state. The excited sensitizer then either decays back to ground state (emitting fluorescence in the process) or undergoes electron spin conversi...
that is, we focus on the case of two heavy fermion singlet or triplet interaction states which is consistent with at least two massive active neutrinos, as is dictated by neutrino oscillation data. The heavy fermion states are assigned 1 and-1unit of LN, respectively. After electroweak symmetry...
states that fluorescence will always originate from the vibrational ground state of the lowest excited singlet level, theS1, while phosphorescence will originate from the vibrational ground state of the lowest excited triplet level, theT1, regardless of which initial level the molecule is excited too...
