✦ Synopsis

Triplet energy transfer from xanthone to 1-methylnaphthalene in the faujasite NaY involves a rapid component which occurs in < 100 ns. This process has been examined with laser techniques. The yields of detectable triplet xanthone and 1-methylnaphthalene are interpreted in terms of a statistical model that assumes that the sphere for energy transfer includes the original excitation supercage and its four nearest neighbor supercages; i.e. the donor and acceptor are not required to be in the same supercage. For 1-methylnaphthalene, extensive self-quenching (occurring in the same distance regime as energy transfer) controls the yields of detectable triplets.

## Abstract It has been demonstrated that the triplet lifetime of nonemitting molecules in the dilute vapor phase ‐ even for complex triplet decays ‐ can be accurately determined by means of time‐resolved triplet‐triplet (T‐T) energy transfer to a strong emitter molecule. Besides the test molecules
