Reflecting the myriad changes and advancements in the technologies involved in FTIR, particularly the development of diamond ATRs, this second edition of Fundamentals of Fourier Transform Infrared Spectroscopy has been extensively rewritten and expanded to include new topics and figures as well as updates of existing chapters. Designed for those new to FTIR, but with enough reference material to appeal to journeyman and expert spectroscopists, this book does not demand any extensive familiarity with chemistry or physics. Specializing in concise and comprehensible explanations of FTIR topics, the author introduces the field of infrared spectroscopy, including the strengths and weaknesses of FTIR as a chemical analysis technique. He then describes the instrument itself and explores topics such as how an interferometer generates a spectrum, optimization of spectral quality, and which tests are used to monitor instrument health. The book discusses how to properly use spectral processing to increase the information of a spectrum without damaging the data and takes considerable care in instructing on sample preparation, as good sample preparation constitutes half the battle in extracting good data. The final chapters examine single analyte quantitative analysis and conclude with an overview of infrared microscopy. Drawing on the experience and knowledge of the author as both a professor and practitioner, Fundamentals of Fourier Transform Infrared Spectroscopy offers up-to-date information given in clear, easily understood language to appeal to beginner and expert spectroscopists alike. The author maintains a website and blog with supplemental material. His training course schedule is also available online.
The aim of this title is to document the meeting exploring the key challenges in understanding the biological chemistry of metals. State of the art work using advanced physical and computational methods to probe the electronic structure and the reactivity at the active sites of metalloenzymes is discussed.

This book addresses the development of electronic devices using redox-active organic molecules and their porous coordination networks (PCNs), and highlights the importance of the molecular arrangement. Redox-active organic molecules hold considerable promise as flexible electronic elements, because their electronic state can easily be controlled using external energy. Although various kinds of redox-active organic molecules have been synthesized, attempts to apply them to electronic devices have been limited, owing to the lack of proper structural design. Moreover, ligand-based redox-active PCNs remain largely unexplored because of the limited availability of redox-active ligands. In addition to developing new redox-active organic molecules, in order to design electronic devices based on these molecules/PCNs, it is essential to understand the connections between their molecular arrangement, electrical properties, and redox activity. In this thesis, the redox-active organic molecule 2,5,8-tri(4-pyridyl)1,3-diazaphenalene (TPDAP), which features a large pi plane and multi-intermolecular interactivity, is used to develop a resistive switching memory device. In addition, its PCNs are synthesized to fabricate chemiresistive sensors, and the electrical properties are modulated using post-synthetic modification. Each mechanism is systematically investigated by means of structural determination and well-defined control experiments. Subsequently, the book proposes general guidelines for designing electronic devices using redox-active organic molecules. The book will appeal to a broad range of readers, from basic scientists to materials engineers, as well as general, non-expert readers.
The 9/11 attack on US soil has inadvertently heightened the need for preparation for other potential means of terrorist attack. In particular, both biological and chemical warfare have been at the top of the priority list for most governmental agencies as these reagents can be covertly prepared and disseminated to result in both widespread fear and casualty. Among many others, one primary preventive step in preparing for the above attacks is to establish a network for efficient surveillance and rapid detection such that an appropriate response to such attacks can be timely and effective. Over the years, primarily due to technological advances, both chemical and biological agents that are able to inflict mass destructions are becoming more diverse and complex. Subsequently, improvement of sensing devices for rapid and sensitive detection should also be made to keep pace with these engineered or emerging threat agents. Of particular interest, the ability to encompass advances in micro and nanofabrication techniques to enable sensing devices are especially of interest as they have been shown to offer desired advantages such as improved and enhanced functionality, increased efficiency and speed in their readout, reduction in their fabrication cost, and also reduced reagent consumption. Numerous innovative and exciting reports which took advantage of these techniques for both chemical and biological sensing have appeared over the last decade. This unique book is the only current publication that provides readers with a brief, yet concise, collection of the latest advances in chemical and biological agent detection and/or their surveillance. It compiles and gives in-depth detail on several detection schemes so that the reader can be provided with a general sense of these micro and nanoscale sensing systems and platforms. The book covers both well established and "next-generation" micro- and nano-scale sensors and/or sensing platforms. Sensors or sensing platforms covered range from the novel utilization of nanotubes, cantilevers, nano and/or microsized pores, engineered whole cell, to polymeric transistors for sensing purposes. As a result of these advances there has been a synergistic marriage of a myriad of techniques, ranging from chemical, engineering and biological, for the development of sensors, which was once traditionally thought to be reserved for the immunologists. The enabling of these new technologies will result in a much improved sensing network for the detection and surveillance of both chemical and biological warfare agents.The book also contains chapters from leading experts in the field of chemical and biological sensing platforms and will be invaluable reading for anybody in this field.

The work presented in this thesis involves a number of sophisticated experiments highlighting novel applications of the Pixel Imaging Mass Spectrometry (PImMS) camera in the field of photoinduced molecular dynamics. This approach represents the union of a new enabling technology (a multiple memory register, CMOS-based pixel detector) with several modern chemical physics approaches and represents a significant leap forward in capabilities. Applications demonstrated include three-dimensional imaging of photofragment Newton spheres, simultaneous electron-ion detection using a single sensor, and ion-ion velocity correlation measurements that open the door to novel covariance imaging experiments. When combined with Coulomb explosion imaging, such an approach is demonstrated to allow the measurement of molecular structure and motion on a femtosecond timescale. This is illustrated through the controlled photoexcitation of torsional motion in biphenyl molecules and the subsequent real-time measurement of the torsional angle.
