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.

Abstract
Fast excitedβstate electron transfer is observed between two chromophores held apart by a rigid saturated steroid moiety.

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-
Atler local photoexci|ation of the accepter chmmophore, fast and virtually barrierless charge separation over approximately 5 A is observed under supersonic jet isolated conditions in three rigid donor-bridge-accepter (D-br-A) systems in which D and A are separated by three o' bonds. It is suggested
