Book Description
New nsec and psec laser spectroscopic techniques are being developed for detect of specific molecular species. In the interest of general applicability, the efficiencies of the methods are being studied and improved by changing from nsec to psec excitation conditions. For specific applications to certain types of agents, we are studying photodecomposition as a method for producting a particular fragment characteristic of that agent-type and which can be detected with high sensitivity and specificity. Keywords include: Laser, Detection, Transients, Remote sensing, Multiphoton ionization, and Transient lens.

Book Description
Molecular and Laser Spectroscopy, Advances and Applications: Volume 3 gives students and researchers an up-to-date understanding of the fast-developing area of molecular and laser spectroscopy. This book covers basic principles and advances in several conventional as well as new and upcoming areas of molecular and laser spectroscopy. This third volume is an extension of the two previous volumes of the same title and includes all-new topics. Each chapter is devoted to a particular fast-growing area of research and fills the gap between elementary texts and advanced material found in research articles. Some of the topics covered include: terahertz spectroscopy and its applications in health care· linear and non-linear vibrational optical activity spectroscopy; cascade laser IR-spectroscopy and frequency comb techniques; step-scan infrared spectroscopy (absorption and emission) for detecting reaction intermediates· surface-enhanced (SERS) and tip-enhanced (TERS) Raman scattering; infrared and Raman micro-spectroscopy; time-resolved linear and non-linear infrared spectroscopy using pico-second and femtosecond lasers. The spectroscopic techniques have been applied to medical sciences, forensics, security, material science, agriculture, food, chemical, pharmaceutical and petrochemical industries and used to study molecular vibrational dynamics, and hydrogen bonding in ground and excited states. This book serves as a valuable resource for students, teachers, and beginning researchers engaged in the area of molecular and laser spectroscopy. On account of the wide range of applications, researchers and scientific personnel in many industries will find this book useful for learning about the latest techniques and putting them to practical use. - Written by eminent research scientists having an intricate knowledge of the latest activities in the field - Includes exhaustive lists of research articles, reviews, and books at the end of each chapter to aid in further pursuit of research activity - Uses illustrative examples of the varied applications to provide a practical guide to those interested in using molecular and laser spectroscopy tools in their research - Each chapter is written in simple, clear language and develops its topic systematically, from basics to the latest developments and future projections

Book Description
This textbook provides an overview of the basics of ultrafast molecular spectroscopy starting from time-dependent quantum mechanical perturbation theory in Hilbert space. It emphasizes the dynamics of nuclear and electronic motion, initiated and monitored by femtosecond laser pulses, which underlie the generation of nonlinear optical signals and inform their interpretation. Topics include short-pulse electronic absorption, the molecular adiabatic approximation, transient-absorption spectroscopy, vibrational adiabaticity during conformational change, femtosecond stimulated Raman spectroscopy, multi-dimensional electronic spectroscopy and wave-packet interferometry, and two-dimensional wave-packet interferometry of electronic excitation-transfer systems. The treatment is based on time-dependent quantum mechanics as it is presented in graduate-level quantum mechanics courses. It is designed to be accessible to beginning practitioners of ultrafast spectroscopy and is meant to serve as a bridge to more advanced treatises and research publications. Numerous exercises are embedded in the text to explore and expand upon the physical ideas encountered in this important research field.

Book Description
Molecular Spectroscopy: Modern Research explores the advances in several phases of research in molecular spectroscopy. This eight-chapter book commemorates the 25th anniversary of the annual Columbus Symposium on Molecular Structure and Spectroscopy, held in September, 1970. This book highlights the spectroscopic studies of molecular species in the gas phase and in matrices. Representative articles are also included that cover the applications of molecular studies in a wide variety of areas such as biophysics, astrophysical problems, and energy transfer processes. Other chapters describe the progress achieved in the technology of high resolution spectroscopy and the techniques and terminology of Lamb-dip spectroscopy. A comprehensive bibliography is included for most of the subjects discussed and this text concludes with tables of standard data listing secondary wavelength standards, fundamental constants, atomic masses, and conversion factors of interest to spectroscopists. Spectroscopists, chemists, and researchers will find this work invaluable.
