Femtosecond time-resolved (pump-probe) laser spectroscopic observations of the dissociative electron transfer (DET) reaction between cisplatin (CDDP) and Rhodamine-B (BV10) in aqueous solutions. (A) Transient absorption measurements of BV10 cation radical (RDM-B+•) in 10 μM BV10 only, 3 mM CDDP only, and the mixtures of 10 μM BV10 and 1.5 mM or 3 mM CDDP. (B,C) Transient absorption measurements of prehydrated electrons (epre) in pure water, 60 μM and 120 μM BV10 only solutions, and in pure water, 3 mM CDDP only and the mixtures of 3 mM CDDP with 60 μM or 120 μM BV10.
