Picosecond transient absorption (TA) and time-resolved infrared (TRIR) measurements of rac-Cr(phen)2(dppz) () intercalated into double-stranded guanine-containing DNA reveal that the excited state is very rapidly quenched. As no evidence was found for the transient electron transfer products, it is proposed that the back electron transfer reaction must be even faster (<3 ps).
对插入到含双链鸟嘌呤的DNA中的外消旋-[Cr(phen)₂(dppz)]³⁺（）进行皮秒瞬态吸收（TA）和时间分辨红外（TRIR）测量，结果表明激发态被非常迅速地淬灭。由于未发现瞬态电子转移产物的证据，因此有人提出反向电子转移反应必定更快（<3皮秒）。
