Direct measurement of ultrafast intersystem crossing time for the (PtBr62-)-Br-IV complex

摘要

The time of ultrafast intersystem crossing for the (PtBr62-)-Br-IV complex in aqueous solution was measured by a fluorescence up-conversion technique. The corresponding time constant (140 +/- 40 fs) is in agreement with that estimated from previous ultrafast transient absorption measurements and with the reported results of theoretical calculations.
