Intersystem Crossing in Gaseous Molecules

The Journal of Chemical Physics, 1967
The theory of electronic relaxation in the solid phase is discussed in terms of gaseous molecules. Two limits are examined—the ``small-molecule limit'' (α limit), where electronic relaxation cannot occur in the free molecule, and the ``big-molecule limit'' (ω limit), where electronic relaxation at a rate virtually identical with that in the solid can ...

Intersystem crossing in photosynthetic pigments

Chemical Physics Letters, 1977
Abstract Intersystem crossing (ISC) of chlorophyll a in solution exhibits a strong solvent dependence and a weak deuterium isotope effect. This is due to the importance of the molecular geometry in promoting ISC. These results are generalized to other closely related photosynthetic pigments.

Quantum beats on intersystem crossing

Journal of Molecular Structure, 1980
Abstract Quantum interference effects in the S 1 → T intersystem crossing and T → S 0 phosphorescence of aza-aromatic molecules are demonstrated. These may arise if the electronic structure of the triplet state T is such that the principal spin-orbit coupling path connects a non-stationary spin state of T with the singlet system.

Influence of Solvent on Carbene Intersystem Crossing Rates

Journal of the American Chemical Society, 2008
The influence of coordinating solvents on singlet-to-triplet carbene intersystem crossing (ISC) rates has been studied with diphenylcarbene (DPC) and para-biphenyltrifluoromethylcarbene (BpCCF 3) by using ultrafast time-resolved spectroscopy. DPC has a triplet ground state in all of the solvents considered, and the concentration of singlet carbene at ...

Intersystem Crossing in Complex Molecules

1980
The general question of singlet-triplet intersystem crossing is addressed in the context of large organic molecules, i.e., “complex” molecules capable of self-relaxation in the absence of collisions. Examples of spectral properties of such molecules in the vapor phase are discussed, relying on extensive Russian literature in this area.

Intersystem Crossing and Multiple Tunnelling

physica status solidi (b), 1969
AbstractThe problem of non‐adiabatic tunnelling in the system of two coupled parabolic terms interacting with the environment has been solved. The model is applied to intersystem crossing in the simple centre of luminescence. The role of multiple passage through the region of term interaction has been cleared up.
