Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Infrared and Raman Spectroscopy focuses on the theoretical and experimental aspects of infrared and Raman spectroscopy, with emphasis on detailed group frequency correlations and their vibrational origin. Topics covered include vibrational and rotational spectra, molecular symmetry, methyl and methylene groups, triple bonds and cumulated double bonds, and olefin groups. Aromatic and heteroaromatic rings are also considered, along with carbonyl compounds and molecular vibrations. This book is comprised of 14 chapters and begins with a discussion on the use of Raman and infrared spectroscopy to study the vibrational and rotational frequencies of molecules, paying particular attention to photon energy and degrees of freedom of molecular motion. The quantum mechanical harmonic oscillator and the anharmonic oscillator are described. The next chapter focuses on the experimental techniques and instrumentation needed to measure infrared absorption spectra and Raman spectra. Symmetry is then discussed from the standpoint of the spectroscopist. The following chapters explore the vibrational origin of group frequencies, with an emphasis on mechanical effects; spectra-structure correlations; and the spectra of compounds such as ethers, alcohols, and phenols. The final chapter demonstrates how the frequencies and forms of a nonlinear molecule's normal modes of vibration may be calculated mathematically. This monograph will be a useful resource for spectroscopists and physical scientists.

Available in PDF, EPUB and Kindle. Book excerpt: This second edition of the successful ready reference is updated and revised with approximately 30% new content to reflect the numerous instrumental developments and improvements, as well as the significant expansion of this rapidly developing field. For example, the combination of IR imaging with AFM has enhanced the achievable lateral resolution by an order of magnitude down to a few hundred nanometers, thus launching a multiplicity of new applications in material science. Furthermore, Raman and IR spectroscopic imaging have become key technologies for the life sciences and today contribute tremendously to a better and more detailed understanding of numerous biological and medical research topics. The topical structure of this new edition is now subdivided into four parts. The first treats the fundamentals of the instrumentation for infrared and Raman imaging and mapping and an overview on the chemometric tools for image analysis. The second part describes a wide varie-ty of applications ranging from biomedical via food, agriculture and plants to polymers and pharmaceuticals. This is followed by a description of imaging techniques operating beyond the diffraction limit, while the final part covers special methodical developments and their utility in specific fields. With its many valuable practical tips, this is a must-have overview for researchers in academic and industrial laboratories wishing to obtain reliable results with this method.

This book was released on 2016 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of the interaction between matter and electromagnetic radiation which procreated the wide branch named as Spectroscopy has gained tremendous attention since the last century. Atoms and molecules respond to electromagnetic radiation to produce their unique spectra which can be used to detect, identify and quantify valuable information about the substance under study. Since, its conception, spectroscopy has been widely used in physical and analytical chemistry and has ramified various techniques depending on the different types of radiation. This dissertation focuses on implementation of various spectroscopic techniques such as Infrared, Raman and Nuclear Magnetic Resonance (NMR) spectroscopy in order to determine theoretical, conformational, qualitative and quantitative properties of different molecules under study. Understanding the physical structure of a molecule is fundamental for function, dynamic, and mechanism studies. Infrared and Raman spectroscopy are two of the most widely used and powerful techniques for the accurate determination of molecular symmetry and conformational stability. They provide information of molecular vibrations and the two techniques complement each other to yield more complete information about the molecular structure than when they are evaluated separately. One of the focus of this dissertation is the determination of the structural parameters, conformational stability, vibrational assignments and ab initio calculations of organic molecules containing five membered ring and phosphorous by utilizing infrared and Raman spectral techniques. The findings of my spectroscopic, structural, and theoretical studies are based on infrared and/or Raman spectra of gas, liquid, solid as well as variable temperature xenon solutions, and microwave spectrum which are supported by ab initio and DFT calculations. Nearly four decades ago the potential of Nuclear Magnetic Resonance (NMR) spectroscopy for the quantitative analysis of organic chemicals was first demonstrated. Along with solution state NMR, for past two decades solid state NMR spectroscopy has also come to the forefront of quantitative analytical techniques in pharmaceutical research, as, both of these techniques have been successfully applied to the study of polymorphism in pharmaceutical drugs at both the qualitative and quantitative levels. The investigation of our research presented in this dissertation was initiated by selecting AIDS, the predominant pandemic of twenty-first century and Tenofovir (TFV), a well-tested antiretroviral drug that has proven its mettle against HIV/AIDS. In order to be able to accurately quantify the amount of drug being delivered in human body is a crucial requirement of any drug development process. We specifically focused on phosphorous containing drugs and hence, a part of this dissertation describes about the development and implementation of a general 31P qNMR method to achieve direct, real time quantification of in vitro drug release. We have effectively utilized both solution state and solid state 31P qNMR spectroscopic techniques to establish the kinetics of drug release and to determine the encapsulation efficiency of nano-formulation for a particular drug under study, respectively. The in vitro drug release profile has been studied in various human body fluids such as simulated vaginal & seminal fluids, plasma etc. depending on the drug under study. The results of method validation parameters for TFV in simulated vaginal & seminal fluid and human plasma obtained by using 31P solution state qNMR spectroscopy are presented in this dissertation. Another chapter of this dissertation explains the analysis of calcined clay as supplementary cementitious material, obtained from Ghana, a West African nation, which does not have an abundance of commonly used SCMs such as fly ash, silica fume, metakaolin, and slag. However, the abundance of clay minerals in the country could provide a sustainable alternative with respect to SCMs application. Qualitative techniques such as Thermal Gravimetric Analysis (TGA) and Forrier Transform Infrared Spectroscopy (FTIR), and quantitative tools like Nuclear Magnetic Resonance (NMR) are able to provide meaningful characterizing of thermally activated clays. In this study, clay from Ghana was thermally activated at temperatures of 600, 700, 800, 900 and 1000oC. The main objective was to characterize calcined clay using TGA, FTIR, NMR, and their relation to pozzolanic activity to best understand the potential of this abundant resource to alleviate cement supply burdens.
