✦ Synopsis

Norbornadiene (l) and quadricyclene (2) undergo photointerconversion in the presence of certain 1,2,3 aromaticketone and -aldehyde triplet sensitizers. The position of the photostationary state thus obtained depends on the triplet energy of the donor. This has been interpreted in terms of a nonspectroscopic excitation of 2 to either the Franck-Condon triplet of 1 or an intermediate biradical; the -
