摘要：

r-1,c-2,t-3,t-4-Tetraphenylcyclobutane (TPCB) was irradiated in n-butyl chloride at room temperature with 20 ns flashes of 265 nm light and in stationary experiments with 260 nm light. trans-Stilbene was found to be formed during the flash with a quantum yield of 0.27. By measuring the optical absorption at 300 nm of the generated trans-stilbene at the end of the flash the conversion of TCPB was determined. It is shown that TPCB-n-butyl chloride is useful as an actinometric system at 265 nm. © 1979.
