A short introduction to Raman spectroscopy, aimed at those interested in integrating Raman measurements to their experiments. We will review what information can be revealed by Raman spectroscopy, fundamental limitations, and typical experimental setups in the context of developments in instrumentation over the last few decades.

Some common applications for Raman spectroscopy will be explored, including chemical identification. A brief and practical overview will be given of some Raman measurement modalities, including resonance Raman, SERS, TERS, mapping, and widefield Raman imaging. We will contrast Raman spectroscopy to its more popular vibrational cousin, infrared absorption.

Learning Objectives

• What information content a Raman spectrum contains. What can be trivially learned from examination of a spectrum, and further what small changes in e.g. peak energies can imply. What’s so special about the so-called “fingerprint region”?
• The minimum experimental requirements for measuring Raman spectra, as well as some specialised variations used for more niche applications.
• In what situations Raman spectroscopy can likely be used, and alternatively, when measurement of Raman spectra is likely impossible due to the fundamental limitations of the technique.
