Intramolecular singlet-singlet energy transfer is reported in a series of compounds containing a 1,4-dimethoxy-naphthalene chromophore as the energy donor and a cyclic ketone as the energy acceptor connected by rigid, elongated, saturated hydrocarbon bridges with an effective length of 4,6, and 8 C-

✦ Synopsis
The comment of Speiser and Rubin regarding the impossibility of long-range, intramolecular exchange energy transfer is refuted by comparison with recent data for other phenomena, e.g. electron transfer, that depend upon electronic interaction between nonconjugatively connected chromophores.

We point out earlier work on intramolecular electronic energy tranfer in bichromophoric molecules and the possibility of an alternative interpretation of the results of Oevering, Verhoeven, Paddon-Row, Cotsaris and Hush.
## Abstract A diad compound 3β(bicyclo[2,2,1]hepta‐2,5‐diene‐2‐methylcarboxylate‐3‐carboxy)‐an‐drost‐5‐en‐17‐one (NBD‐S‐ONE) was synthesized and its photochemistry was examined. Irradiation of NBD‐S‐ONE in acetonitrile at λ > 300 nm selectively excited the keto chromophore. After intersystem crossi
