[Ru(bpy)3]2+ was excited using 351 nm 20 ns pulses at 5.7 mJ/cm2 of fluence. The FT-IR was operated at 100 Hz, collecting 10 spectra while averaging 30 pulses per step. (A) Ground-state absorption spectrum of [Ru(bpy)3]2+. (B) The difference spectrum associated with photo-excitation of [Ru(bpy)3]2+ graphed as laser on absorbance minus reference absorbance. (C) Excited-state spectrum obtained by adding 7.3% of the ground-state spectrum to the photo-excitation difference spectrum.
