Raman spectroscopy

Abstract

This chapter reviews the theory of Raman spectroscopy. Raman instrumentation and components are reviewed including lasers, spectrometers, detectors, dispersive Raman, and interferometric Fourier transform Raman instruments. Advances in process Raman measurements with fiber-optic probes are also outlined. Viable approaches to the use of Raman spectroscopy as a process analytical technology (PAT) tool in the food industry is discussed along with the challenges of adapting this technology to the process environment.
