This book presents the fundamental principles and experimental techniques of laser spectroscopy. It explains laser sources, spectroscopic methods, instrumentation, and applications in physics and chemistry, providing a detailed reference for students and researchers working in optical spectroscopy and laser physics.
A technical reference bridging quantum chemical theory with experimental spectroscopic practice. Chapters cover the Born–Oppenheimer approximation, electronic states, potential energy surfaces, rotation‑vibration theory, rovibronic effects, and molecular dynamics. The book offers both theoretical frameworks and practical examples for interpreting and predicting high‑resolution molecular s…
