Abstract

This is the first report describing the use of picosecond time-resolved infrared (TRIR) spectroscopy to probe a d⁸ metal chromophore, Pt(4,4′-(CO₂Et)₂-2,2′-bpy)Cl₂: monitoring changes in the ν(CO) vibrations allows for an assignment of the lowest excited state to an MLCT with an 8.7 ps lifetime.
