| Year of publication: | 1985 |

| Summary: |
The deactivation pathway of the thionine triplet (3 TH +) in pyridine was investigated using microsecond laser flash spectroscopy. It was found that the electronic relaxation of the triplet 3 TH + occurs via protolytic dissociation to the triplet 3 T which, after radiationless decay to the ground state T, is reprotonated to TH +. The unique feature of this deactivation pathway is that is represents a Förster cycle where all steps can be conveniently followed by flash spectroscopy in the microsecond time regime. The energy of the triplet state 3 T was estimated to be 150 ± 6 kJ mol -1.
