| 摘 要： | Excitation energy transfer in phycoerythrocyanins (PEC) was studied by use of computer simulation. The results observed from the simulation are as follows: (i) The α84 is a more efficient sensitizing chromophore than β155 and donates the excitation energy into β84 and β155 while it scarcely emits fluorescence itself, (ii) Only the 1α84 →2β84 is the sub-picosecond process in a PEC trimer, therefore it is readily to obtain the time constant from fs-level time-resolved spectral measurement. (iii) The β84 and β155 chromophores in PEC behave quite differently from those in C-PC because of the changes in α84. It is observed that 1β156→6β155 is the dominant pathway linking two trimers and both of the chromophores possess much higher fluorescence fractions, and about 80% of the total fluorescence is emitted from the β84 chromophore. (iv) A far less mean number of transfer times is observed through the fast-transfer pairs in PEC compared with that in C-PC because of slow transfer rate for the path
