triplet state


triplet state

[′trip·lət ‚stāt] (atomic physics) Electronic state of an atom or molecule whose total spin angular momentum quantum number is equal to 1. (quantum mechanics) Any multiplet having three states.

triplet state


trip·let state

a second excited state of a molecule (for example, chlorophyll) produced by absorption of light to produce the singlet state, then loss of some energy (fluorescence) to achieve the longer-lasting triplet state The molecule may remain sufficiently long in the triplet state for a second activating light quantum to be effective in producing a "second triplet" state, at a still-higher level of excitation, hence reactivity. Alternatively, the molecule may lose the triplet state energy directly and return to the ground state.
