Surface-Enhanced Vibrational Spectroscopy

Surface Enhanced Vibrational Spectroscopy (SEVS) has reachedmaturity as an analytical technique, but until now there has beenno single work that describes the theory and experiments of SEVS.This book combines the two important techniques of surface-enhancedRaman scattering (SERS) and surface-enhanced infrared (SEIR) intoone text that serves as the definitive resource on SEVS. * Discusses both the theory and the applications of SEVS andprovides an up-to-date study of the state of the art * Offers interpretations of SEVS spectra for practicinganalysts * Discusses interpretation of SEVS spectra, which can often bevery different to the non-enhanced spectrum - aids the practicinganalyst
