Offers a complete overhaul and update of the original edition, while continuing to balance thorough treatment of fundamentals with key practical tools for the interpretation of spectra
Includes more sample spectra and analyses, worked examples, and homework problems
Presents introductory chapters on quantum mechanics, electromagnetic radiation, and electrostatics, along with appendix materials for a math review and group theory essentials, making it a stand-alone text
Adds chapters on nonlinear optical spectroscopy, covering techniques such as photon echo, sum-frequency generation, and multiphoton absorption; also adds chapters on time-resolved optical spectroscopy with discussion of Raman, fluorescence, infrared, and hole burning
Utilizes extensive illustrations to reinforce important concepts and retains the same highly readable and lively style of the prior edition
Summary

This textbook offers an introduction to the foundations of spectroscopic methods and provides a bridge between basic concepts and experimental applications in fields as diverse as materials science, biology, solar energy conversion, and environmental science. The author emphasizes the use of time-dependent theory to link the spectral response in the frequency domain to the behavior of molecules in the time domain, strengthened by two brand new chapters on nonlinear optical spectroscopy and time-resolved spectroscopy. Theoretical underpinnings are presented to the extent necessary for readers to understand how to apply spectroscopic tools to their own interests
