摘要：

Splitting of UV absorption bands of the substituted pyridinyl radicals by formation of CT type dimers is discussed using an esciton model. From observed results and theoretical considerations a kind of twisted model is proposed in the dimer, where the two radicals lie one above the other in parallel planes, but are rotated from each other by a small angle around an axis perpendicular to the molecular planes. This twisted model may be ascribed to steric hindrance of bulky substituents to the dimer formation.
