We report resonance Raman (RR) spectra of the singlet S 1 and triplet T 1 excited states of zinc(II) octaethylporphyrin (ZnOEP) and zinc(II) etioporphyrin-I (ZnEtio), using picosecond and nanosecond RR techniques. Picosecond time-resolved resonance Raman experiments were performed using 532 ...
Energy ordering of singlet and triplet excited states in indacenodithiophene and indenofluorenes molecules in singlet fission: A model exact and density matrix renormalization group studyEnergy ordering of lowest singlet ( S 1 ) and triplet excited state ( T 1 ) dominates the optoelectronic ...
Hund’s multiplicity rule states that a higher spin state has a lower energy for a given electronic configuration1. Rephrasing this rule for molecular excited states predicts a positive energy gap between spin-singlet and spin-triplet excited states, as has been consistent with numerous experimental...
