Ultrasensitive Laser Spectroscopy

Ultrasensitive Laser Spectroscopy covers the experimental methods involved in various sensitive techniques to which lasers have been applied for the study of weak transitions.
This book is organized into seven chapters. Each chapter discusses the theories, experiments, and application of the specific technique. A discussion on the advantages, disadvantages, and modifications made in each technique is also provided. Ultrasensitive techniques considered in this text include photoacoustic, one- and two-photon excitation, absorption, mass, and laser ionization spectroscopies. Other chapters examine the techniques of laser intracavity-enhanced, laser absorption, and emission spectroscopy.
This book will be of value to spectroscopists, analytical chemists, and researchers in the field of ultrasensitive analysis.
