In this chapter, we describe Raman microspectrophotometry applied to crystals of biomolecules. Raman spectra collected in crystallo provide structural information highly complementary to X-ray diffraction, relate the crystalline state to the solution state, and allow the identification of ligand-bound or intermediate states of macromolecules. Nonresonant Raman spectroscopy is particularly suitable to the study of macromolecular crystals, and therefore applies to a wide range of noncolored crystalline proteins. Practical issues related to the investigation of crystals by Raman microspectrophotometry are reviewed, and the current limitations are highlighted.
