Description
The radiationless decay rate constants of the zero field spin sublevels of the lowest triplet state of meso-tetra (m-fluorophenyl) porphin free base are reported. The values for the free base deuterated at the N-H positions are also given. Deuteration affects the fast in-plane spin state more than the slow in-plane spin state. The role of out-of-plane N-H vibrations as promoting modes is discussed in terms of the theory of Metz and co-workers. (Auth.)
