摘要：
The photoinduced intramolecular energy-transfer (ET) reaction between benzophenone (BP) and norbornadiene (N) covalently bonded by a rigid steroid bridge in acetonitrile has been studied by laser flash photolysis. The ET rate constant for the excited triplet BP ((BP)-B-3*) to N is 6.1x10(4) s(-1), whereas the constant for the intramolecular hydrogen atom abstraction of (BP)-B-3* from the steroid is 1.91x10(5) s(-1).
