Triplet Pair States in Singlet Fission

Chemical Reviews, 2019
This account aims at providing an understanding of singlet fission, i.e., the photophysical process of a singlet state ( S1) splitting into two triplet states (2 × T1) in molecular chromophores. Since its discovery 50 years ago, the field of singlet fission has enjoyed rapid expansion in the past 8 years.

Carotenoid triplet state lifetimes

Journal of Photochemistry and Photobiology B: Biology, 2000
Carotene and xanthophyll triplet lifetimes are found to depend on the concentration of the parent molecule. These results account for some of the variations in carotenoid triplet lifetimes reported previously. The rate constants obtained for ground state quenching correlate with the number of conjugated double bonds, the longer chain systems having ...

Triplet State of DNA

The Journal of Chemical Physics, 1967
Additional proof has been obtained for the fact that the triplet state in DNA and poly dAT resides at the thymine residue by comparing the intensities of the triplet ESR and phosphorescence signals from DNA's from various sources having different (A+T)/(G+C) ratios.

Triplet states in photosynthesis

Biochemical and Biophysical Research Communications, 1974
Abstract A comparison of zero field splitting (ZFS) and spin polarization of triplet spectra of bacteriochlorophyll a in vitro and in vivo provides support for the special pair model of photoreactive chlorophyll in photosynthetic bacteria.

Photodissociation of N2O: Triplet states and triplet channel

The Journal of Chemical Physics, 2011
The role of triplet states in the UV photodissociation of \documentclass[12pt]{minimal}\begin{document}$\rm N_2O$\end{document}N2O is investigated by means of quantum mechanical wave packet calculations. Global potential energy surfaces are calculated for the lowest two 3A′ and the lowest two 3A′′ states at the multi-reference configuration interaction
