The book "Surface-Enhanced Raman Scattering" offers a comprehensive analysis of the phenomenon of surface-enhanced Raman scattering (SERS), which has been intensively researched for nearly 30 years. Despite the widespread establishment of SERS, the explanation of the signal enhancement by fourteen orders of magnitude remains a fascinating topic for physicists and chemists. This textbook illuminates the theoretical approaches developed to explain SERS and presents the latest experiments and applications that highlight the versatility and relevance of this spectroscopic technique across various scientific disciplines. The authors, Katrin Kneipp, Martin Moskovits, and Harald Kneipp, contribute their expertise to guide readers through the complex concepts and exciting possibilities that SERS offers.
