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.
