摘要
采用ICCD皮秒、飞秒扫描成象光谱装置研究PSⅡ核心复合物激发能传递光谱特性，获得的PSⅡ积分荧光谱从661nm到693nm，峰值波长680nm，有四个组分谱，谱的峰值分别为670nm、676nm、681nm、686nm。CP43有Chl a６６１６６０、Chl a６７０６６９和Chl a６８６６８２三个光谱组分；CP47有Chl a６61６６0、Chl a６７０６６９和Chl a６81６80三个光谱组分。根据吸收光谱和组分光谱分析，PSⅡ核心天线各自有三种不同状态的Chl a分子，它们是CP43-Chl a６61６60、CP43-Chl a６70６69、CP43-Chl a６86６82与CP47-Chl a６61６60、CP47-Chl a６70６69、CP47-Chl a６81６80。通过四个光谱组分分析了PSⅡ核心复合物激发能传递的光谱特性.
Spectra characteristics of energy transfer in PSⅡ co re complex had been studied by using femtosecond scanning imaging spectrograph.P SⅡ integral fluorescence spectrum was from 661nm to 693nm with peak at 680nm,an d had four component spectrum,they were 670nm,676nm,681nm,686nm.CP43 core antenn a had three spectrum components,viz Chl a６６１６６０,Chl a６７０６６９,Chl a６８６６８２.CP47 core antenna also had three spectrum components,viz Chl a６６１６６０,Chl a６７１６６ ９，Chl a６８１６８０.Each of PSⅡ core antenna ha d three Chla molecules of different condition,they were CP43 Chl a６６１６６０,CP43 Chl a670６６9,CP43 Chl a686６82,CP47 Chl a661 ６６0,CP47 Chl a671６６9,CP47 Chl a 681６80,respectively.Spectra characteristics of excitation e nergy transfer in PSⅡ core complex had been analyzed by four spectrum components.
