a quantum efficiency of 0.3 under 365-nm irradiation. Transient absorption spectroscopy shows that this ring closure proceeds via two intermediates. The first decays in a unimolecular process (k/sub 2/ = 3.8 +/- 0.4 x 10/sup 6/ s/sup -1/) to produce the second which also decays unimolecularly (k/sub 3/ = 4.6 +/- 10/sup 4/ s/sup -1/) to yield PPF.
