The photoinduced absorption and bleaching of trans-(CD). and trans-(CD). in thenanosecond time region were investigated for the first time by time-resolved absorp-tion spectroscopy. The transient absorption near the band gap and the bleaching ofthe interband transition were observed for both Zr*os-(CH).and trans-(CD).. The ab-sorption near the band gap saturated at AA/A.?O.OI. The decay of transient absorp-lion at 4K was fitted to erf[(Z/r) "'] with r=144fl5ns for trans-(CD). andr=305:27 ns for trans-(CD).. When the temperature is increased, the decay kineticsare given by the same function with shorter time constants, r=32H6 ns for trans-(CH), and r=4O"6 ns for trans-(CD). at 290 K. When the trans content in c7,v-richfilm decreased, the time constant became longer. The decay kinetics is interpreted byinterchain recombination of photoinduced polaron pairs.
