It is shown that the fluorescence and intorsystem crossing in monocyclic diazines originate from the second excited singlet state (S$. The occurrence of these phenomena is justified on the basis of the slow S, -E+ internal conversion resulting from the low density of states.
The quantitative interpretation of the fluorescence quenching of anthracene in various solvents based on a recently deveIoped theory of radiationless transitions is given. It is shown that high temperature results can be expIained in terms of the Sl-+ Ta transition only\_ so there is no need to assu
