Book Description
The advent of laser-based sources of ultrafast infrared pulses has extended the study of very fast molecular dynamics to the observation of processes manifested through their effects on the vibrations of molecules. In addition, non-linear infrared spectroscopic techniques make it possible to examine intra- and intermolecular interactions and how such interactions evolve on very fast time scales, but also in some instances on very slow time scales. Ultrafast Infrared Vibrational Spectroscopy is an advanced overview of the field of ultrafast infrared vibrational spectroscopy based on the scientific research of the leading figures in the field. The book discusses experimental and theoretical topics reflecting the latest accomplishments and understanding of ultrafast infrared vibrational spectroscopy. Each chapter provides background, details of methods, and explication of a topic of current research interest. Experimental and theoretical studies cover topics as diverse as the dynamics of water and the dynamics and structure of biological molecules. Methods covered include vibrational echo chemical exchange spectroscopy, IR-Raman spectroscopy, time resolved sum frequency generation, and 2D IR spectroscopy. Edited by a recognized leader in the field and with contributions from top researchers, including experimentalists and theoreticians, this book presents the latest research methods and results. It will serve as an excellent resource for those new to the field, experts in the field, and individuals who want to gain an understanding of particular methods and research topics.

Book Description
Ultrafast infrared 2D-IR vibrational echo experiments were extended experimentally and theoretically. Detailed studies of water dynamics were performed and compared to MD simulations. 2D-IR vibrational echo chemical exchange experiments were used to study the formation and dissociation kinetics of eight solute-solvent complexes, and the results were related to the enthalpies of formation. MD simulations of the chemical exchange were performed for the phenol-benzene complex and found to be in good agreement with the data. Chemical exchange experiments were used to measure the rate of gauche-trans orientational isomerization about a carbon-carbon single bond. The dynamics of molecules in the first solvation shell of solutes in mixed solvents were studied, and the time dependent solvent compositional fluctuations about solutes were elucidated. A detailed time dependent diagrammatic perturbation theory of the 2D-IR vibrational echo chemical exchange experiment including spectral diffusion, orientational relaxation, and vibrational relaxation was developed. An important new theoretical method for determining the dynamics from 2D-IR vibrational echo experiments was developed and demonstrated.

Book Description
2D infrared (IR) spectroscopy is a cutting-edge technique, with applications in subjects as diverse as the energy sciences, biophysics and physical chemistry. This book introduces the essential concepts of 2D IR spectroscopy step-by-step to build an intuitive and in-depth understanding of the method. This unique book introduces the mathematical formalism in a simple manner, examines the design considerations for implementing the methods in the laboratory, and contains working computer code to simulate 2D IR spectra and exercises to illustrate involved concepts. Readers will learn how to accurately interpret 2D IR spectra, design their own spectrometer and invent their own pulse sequences. It is an excellent starting point for graduate students and researchers new to this exciting field. Computer codes and answers to the exercises can be downloaded from the authors' website, available at www.cambridge.org/9781107000056.

Book Description
This unique volume presents a comprehensive but accessible introduction to the field of ultrafast two-dimension infrared (2D IR) vibrational echo spectroscopy based on the pioneering work of Professor Michael D Fayer, Department of Chemistry, Stanford University, USA. It contains in one place a qualitative introduction to the field of 2D IR spectroscopy and a comprehensive set of scientific papers that underlie the qualitative discussion. The introductory material contains several detailed illustrations, and is based on the Centenary Lecture at the Indian Institute of Science given by Professor Fayer July 16, 2008 as part of the celebration of the 100th anniversary of the founding of IIS in Bangalore, India. The second part of the volume contains reprints of Fayer's relevant papers. The compilation will be very useful because it presents the historical background, motivation, methodology, and experimental results at a level that is accessible to the non-expert. The reprints of the scientific papers, from review articles to detailed theoretical papers, provide rigorous supporting material so that the reader can delve as deeply as desired into the subject.

Book Description
Infrared pump-probe experiments were used to study vibrational relaxation of polyatomic molecules in supercritical fluids and the gas phase. IR pump-probe experiments and theory were used to investigate hydrogen bond dynamics in oligomers of alcohols. Vibrational echo correlation spectroscopy (VECS) was developed and experiments were performed on molecules in liquids and gases. VECS is an ultrafast multidimensional approach that is in many respects the vibrational equivalent of multidimensional NMR. VECS experiments have been performed on molecules in liquids and gases. The OD hydroxyl stretch of HOD in water was studied and the results were compared to theoretical simulation models of water. The time evolution of the vibrational echo correlation spectrum reflects the structural evolution of the hydrogen bond networks in water. The experiments and theory provide detailed tests of water models. A gas cell for performing ultrafast infrared experiments was developed and the first vibrational echo correlation spectroscopy experiments were performed in the gas phase. VECS was also been demonstrated as a new type of analytical tool that can aid in sorting out congested vibrational spectra.

Book Description
The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Book Description
The remarkable properties of glassy materials arise from their complex amorphous structures and dynamics. The heterogeneity of these materials was studied on molecular length scales and picosecond time scales using a combination of polarization-selective IR pump-probe and 2D IR experiments and a vibrational chromophore that is sensitive to local chemical and electrical environments. By monitoring the restricted orientational motion of the chromophore in a polymer, the distribution of sub-nanometer pores could be explored. The same chromophore in a hydrogen-bonding system showed extreme polarization dependence in the 2D line shape, providing evidence for significant dynamical heterogeneity in the supercooled liquid phase.
