Abstract

Abstract: Two different AS= 2 intersystem crossing processes, the'MLCT-) T2 and ST2-'A, conversions which follow the photoexcitation of low-spin Fe" complexes, are examined on the nanosecond, picosecond, and subpicosecond time scales. Aqueous solutions of the complexes [Fe (tpen)](C104) 2,[Fe (tptn)](C104) 2,[Fe (t-tpchxn)](C104) 2,[Fe (bpy),](C104) 2,[Fe-(phen) 3](C104) 2, and [Fe (terpy) 2](C104) 2 are studied, where in the first three ...
