Step-scan Fourier transform absorption difference time-resolved spectroscopy (S2FTIR ∆A TRS) has been used to collect mid-IR time-resolved infrared spectra of the transient electronic excited states of polypyridine transition metal complexes with 10 ns time resolution. The time-resolved data can be used for kinetic analysis or to generate “snapshots” of the lowest lying excited state. Shifts of vibrational bands in the excited state relative to the ground state can be used to infer significant details of the electronic structure of the excited state. The multiplex advantage of the FTIR technique allows a wide variety of vibrational bands to be analyzed for this purpose. In the example illustrated, the shift of the ester ν(CO) band in {Ru(bpy)[4,4′-(COOEt)2bpy]2}2+ compared to those in related complexes has been used to address the question of electron delocalization in the excited state.

A newly designed multichannel Fourier transform infrared spectrometer has been constructed for single-event time-resolved spectroscopy. It is capable of measuring unrepeatable transient events such as phase transitions, explosions, etc., with a time resolution of up to 5.14 ms. The mid-infrared region of 4500–2500 cm−1 is covered with a maximum spectral resolution of 13 cm−1. The developed system is used to measure the phase transitions of alkanes. The solid–solid and solid–liquid phase transitions of octadecane and nonadecane have been studied with time resolutions of 5–50 ms.
