Atomic Spectroscopy and Radiative Processes

Focusing on atomic spectroscopy, this book explores the absorption and emission of radiation in both astrophysical and laboratory plasmas. It covers fundamental principles of electromagnetism and thermodynamics, delving into the theory of atomic spectra for complex atoms with an emphasis on astrophysical contexts. The text addresses both equilibrium and non-equilibrium plasma phenomena, detailing the interaction between radiation and matter, various radiation types, and the theory of polarization and radiative transfer. It's designed for undergraduates and postgraduates, offering a comprehensive understanding supported by practical applications.
