TL;DR: In this article, a step-scan Fourier transform infrared spectroscopy (FTIR) method was proposed to study the electronic excited states of transition metal complexes, taking advantage of the unique properties of carbonyl and cyanide stretching vibrations, including high infrared oscillator strength and well established sensitivity of vibrational frequency, intensity, and bandwidth to electronic and molecular structure.
Abstract: Time-resolved, step-scan Fourier transform infrared spectroscopy has been developed as a method of studying electronically excited states of transition metal complexes. The technique takes advantage of the unique properties of carbonyl and cyanide stretching vibrations, including high infrared oscillator strength and well established sensitivity of vibrational frequency, intensity, and bandwidth to electronic and molecular structure. Electronic excitation generally produces significant transient infrared absorption changes which are characteristic of the changes in electronic structure, such as oxidation of the metal. TRIR spectroscopy thus provides new insight on the nature of the excited state transition (e.g. charge transfer vs. ligand centered), the extent of charge transfer, communication between metal centers, and energy and electron transfer processes. The step-scan FTIR approach has significant advantages over conventional time-resolved techniques, including spectral multiplexing, increas...

TL;DR: Fourier transform infrared (FTIR) spectroscopy is a powerful, nonperturbing technique that has been used to good effect for the detection and characterization of lipid phase transitions in model and natural membranes.
Abstract: Fourier transform infrared (FTIR) spectroscopy is a powerful, nonperturbing technique that has been used to good effect for the detection and characterization of lipid phase transitions in model and natural membranes. The technique is also quite versatile, covering a wide range of sophisticated applications, from which fairly detailed information about the structure and organization of membranes and other lipid assemblies can be obtained. In this chapter, an introduction to this particular application of FTIR spectroscopy is presented. Special emphasis is put on how the technique can be used to study lipid phase transitions under biologically relevant conditions. The chapter is intended to give an overview of the capabilities of FTIR spectroscopy in the field of lipid and biomembrane research, and provide the reader with some practical guidelines for the design and execution of simple FTIR spectroscopic experiments suitable for the detection and characterization of lipid phase transitions in hydrated lipid bilayers.
