Excited State Structure and Relaxation Dynamics of Polypyridyl Complexes of Low Spin d6 Metal Ions by Means of Step-Scan FTIR Time-Resolved Spectroscopy (S2FT-IR TRS)
Time-resolved infrared spectroscopy has been applied to study the excited state dynamics of many biological molecules and transition metal complexes following laser-flash excitation [1–6]. The short lifetimes of the excited states involved in these processes require very high time resolution. Until recently, fast time-resolved IR measurements have typically utilized tunable IR diode lasers as the probe source. The limited tunability of these IR lasers limited the studies to systems that contain CO or CN groups as a “reporter” ligand.
