To remove some of the limitations imposed by the approaches mentioned above, Fourier transform infrared (FTIR) imaging has been developed as a high-throughput technique for the study of heterogeneous catalysts.21,22 By combining an array...

This technique uses the detection of spins of nuclear magnetic moments to produce a virtual section in the organ. Fourier-Transform InfraRed (FTIR) imaging, X-ray imaging or even the techniques of imaging by tomography help to obtain resolutions near the micrometer. These techniques are particularly useful for identifying stmctural chemical elements and also, in some cases, specialized metabolites. 

It is clear that the introduction of the IR FPA detector has brought Fourier transform infrared (FTIR) microscopy with a thermal source to a new and exciting stage of development. This is illustrated in the other chapters of this volume. Our purpose in this chapter is to address how IR FPA technology could be combined with the synchrotron source to advance IR spectroscopic imaging in ways that would prove quite difficult with a conventional thermal source. To address this question, we will need to understand the detailed nature of the synchrotron IR source, the optical... 

Fourier-Transform Infrared (FTIR) spectroscopy as well as Raman spectroscopy are well established as methods for structural analysis of compounds in solution or when adsorbed to surfaces or in any other state. Analysis of the spectra provides information of qualitative as well as of quantitative nature. Very recent developments, FTIR imaging spectroscopy as well as Raman mapping spectroscopy, provide important information leading to the development of novel materials. If applied under optical near-field conditions, these new technologies combine lateral resolution down to the size of nanoparticles with the high chemical selectivity of a FTIR or Raman spectrum. These techniques now help us obtain information on molecular order and molecular orientation and conformation [1],... 

Fourier transform infrared (FTIR) and Raman spectroscopy can provide important structural information on the molecular composition of a sample as well as relative quantification of lipids, proteins, carbohydrates and a variety of phosphorylated biomolecules within cells or tissue. However, sample preparation is the key to realizing the full potential of these technologies. This element of the experimental design can have a significant impact on the interpretation of spectra for their biochemical relevance and on the spatial distribution of biomolecules in imaging studies. 

In polymer processing, whether it is a blending, annealing or diffusion process, it is vital to characterize the chemical composition and spatial distribution of the materials involved. Fourier transform infrared (FTIR) spectroscopy has traditionally been used as a powerful nondestructive material identification method, as well as an important tool to study intermolecular interactions and different polymer morphologies. With the introduction of infrared (IR) microscopes and array detectors, chemical imaging using FTIR spectroscopy has become an established tool in polymer analysis. 

The morphology and component distribution were performed by optical microscopy, scanning electron microscopy (FBI make, model QUANTA-2000), transmission electron microscopy (JEOL make, model 2000FX), atomic force microscopy (Molecular Imaging Ltd., USA, model Pico Scan). The functional groups present in composite materials were evaluated by spectroscopic absorption study in Fourier transformation infrared (FTIR) analyzer (Broker make, model Vector 22).
