The intramolecular electronic energy transfer between two chromopliorcs separated by a methylene chain has been observed in an isolated molecule. The molecules studied are 1 \_(o-tolyl)-3-@-tolyl)propane (I) and I-(m-tolyl)-3-@-tolylk propane (II). The energy transfer rate from o-or m-xylcnc moiety

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.
