Available in PDF, EPUB and Kindle. Book excerpt: Although infrared spectroscopy has been applied with success to the study of important biological and biomedical processes for many years, key advances in this vibrant technique have led to its increasing use, ranging from characterisation of individual macromolecules (DNA, RNA, lipids, proteins) to human tissues, cells and their components. Infrared spectroscopy thus has a significant role to play in the analysis of the vast number of genes and proteins being identified by the various genomic sequencing projects. Whilst this book gives an overview of the field it highlights more recent developments, such as the use of bright synchrotron radiation for recording infrared spectra, the development of two-dimensional infrared spectroscopy and the ability to record infrared spectra at ultrafast speeds. The main focus is on the mid-infrared region, since the great majority of studies are carried out in this region but there is increasing use of the near infrared for biomedical applications and a chapter is devoted to this part of the spectrum. Major advances in theoretical analysis have also enabled better interpretation of the infrared spectra of biological molecules and these are covered. The editors, Professor Andreas Barth of Stockholm University, Stockholm, Sweden and Dr Parvez I. Haris of De Montfort University, Leicester, U.K., who both have extensive research experience in biological infrared spectroscopy per se and in its use in the solution of biophysical problems, have felt it timely therefore to bring together this book. The book is intended for use both by research scientists already active in the use of biological infrared spectroscopy and for those coming new to the technique. Graduate students will also find it useful as an introduction to the technique.
Download or read book Linearly Polarized IR Spectroscopy written by Bojidarka Ivanova and published by CRC Press. This book was released on 2024-11-01 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: A technique that is useful in the study of pharmaceutical products and biological molecules, polarization IR spectroscopy has undergone continuous development since it first emerged almost 100 years ago. Capturing the state of the science as it exists today, Linearly Polarized IR Spectroscopy: Theory and Applications for Structural Analysis demonstrates how the technique can be properly utilized to obtain important information about the structure and spectral properties of oriented compounds. The book starts with the theoretical basis of linear-dichroic infrared (IR-LD) spectroscopy and then moves on to examine the background of the orientation method of colloid suspensions in a nematic host. It explores the orientation procedure itself, experimental design, and mathematical tools for the interpretation of the IR spectroscopic patterns. Next, the authors describe the structural elucidation of inorganic and organic compounds and glasses. Finally, they discuss applications in pharmaceutical analysis and the chemistry of dyes. Filled with more than 140 illustrations along with a color insert, the book explains both the scope of the polarized IR spectroscopy method as well as its limitations. A powerful source of information not only for specialists in IR spectroscopy, but also for those working in the field of structural analysis, this volume moves the field closer to developing an inherently classical method for the structural characterization of compounds.
Download or read book Tables of Wavenumbers for the Calibration of Infrared Spectrometers written by A.R.H. Cole and published by Elsevier. This book was released on 2016-04-20 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tables of Wavenumbers for the Calibration of Infrared Spectrometers, Second Edition is a compilation of tables of wavenumber values for the calibration of infrared spectrometers. It makes the best use of high resolution results and integrates the far infrared data with the higher frequency values. This book is organized in two parts, one for high to medium-resolution spectrometers used by physical chemists and physicists, and the other for medium to low-resolution instruments employed by organic and inorganic chemists. The first part includes tables of wavenumber of infrared absorption lines in spectra of gaseous molecules as well as procedures for using the tables, including the calibration-curve method, the method of overlapping orders (superposition method), and atomic line method. The calibration tables are illustrated by infrared spectra obtained under a variety of conditions. The second part includes vapor, liquid, and solid phase calibrants for small spectrometers. This monograph will be a valuable resource for physicists, chemists, and spectroscopists.
Download or read book Infrared Measurements of the Vibrational Excitation and De excitation Rates of N2 Using CO Additive written by Anthony L. Russo and published by . This book was released on 1968 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shock wave and nozzle expansion flow studies have been made of the vibrational relaxation of N2 in a 95% N2 + 5% CO test gas mixture by observing the infrared optical activity of the CO. The large cross section for vibration-vibration exchange between N2 and CO permits the vibrational temperature of the N2 to be inferred from band reversal measurements of CO. Behind shock waves with equilibrium temperatures in the range of 1500K - 2100K the vibrational relaxation rates for N2 obtained by this method are shown to be in good agreement with previous measurements of the N2 vibrational relaxation rate. In nozzle expansion flows of the same test gas from reservoir temperatures of 2800K - 4000K and reservoir pressures of about 50 atm, the vibrational temperatures of N2 are found to be much closer to equilibrium values than predicted using the relaxation rates determined behind shock waves. These observations are in complete agreement with results obtained earlier in the N2 by line-reversal spectroscopy. Both N2 and CO have been observed to exhibit faster rates for vibrational de-excitation in nozzle flows than predicted using vibrational rate data obtained in the shock wave excitation environment.

Download or read book Simulating a Chromotomographic Sensor for Hyperspectral Imaging in the Infrared written by Anthony J. Dearinger and published by . This book was released on 2004-03-01 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hyperspectral imaging systems passively sense radiant electromagnetic energy from a remote scene to form a three dimension profile of the remote scene. The data contained in this profile describes real images of the remote scene for a certain number of spectral wavelength bands across a finite spectral range of electromagnetic radiation. Typical grating type hyperspectral imaging systems collect spectral electromagnetic radiation in the visible and near infrared spectral range, by incrementally scanning across the spatial extent of the remote scene. The legacy of low optical throughput because of the optical scanning techniques employed in these systems means adapting these systems for spectral ranges extending into the mid wave and long wave infrared is difficult. A chromotomographic imaging system utilizing a sensor optics system with significantly greater optical throughput of electromagnetic radiation has been reported to demonstrate reasonable quality hyperspectral images for finite spectral ranges in the visible, mid wave, and long wave infrared. The spectral electromagnetic radiation collected through the sensor optics system angularly multiplexes the electromagnetic radiation collected from the remote scene using a rotating prism to disperse and spatially separate the electromagnetic radiation spectral components onto a focal plane array detector. Using optics principles and wave optics propagation theory, a software model was designed based on linear systems principles to emulate the point spread function attributes of the chromotomographic sensor, equivalent to the impulse response for a linear system.
